The Netherlands has a long tradition in theoretical physics which involves research performed at university institutes, industrial laboratories, and government institutions. The strength of this research area is, for a large part, based on the unity of methods employed in a wide range of applications. This manifests itself both in sci- entiﬁc research and in academic education.

To structure and coordinate the graduate education in theoretical physics, the Dutch Research School of Theoretical Physics (DRSTP) was formed. The school is a cooperation between the theoretical physics groups of six Dutch universities: University of Amsterdam (UvA), Vrije Universiteit Amsterdam (VUA), University of Gronin- gen (RUG), Leiden University (UL), Radboud University Nijmegen (RU), Utrecht University (UU) (commissioner) and of the National Institute for Subatomic Physics (Nikhef). In addition, there are several associate members. The DRSTP was accredited in 1994 by the Royal Netherlands Academy of Arts and Sciences (KNAW) and reaccredited in 1999, 2004 and 2010.

The main objectives of the DRSTP are to implement a joint program of graduate education in theoretical physics and to maintain and strengthen research in theoretical physics from a broad unifying perspective that exploits the interrelationships between different fields of theory. The DRSTP is based on the conviction that a joint venture of all the moderately sized local theory groups, each with its own profile, offers added value for the achievement of these objectives.

Theoretical physics is based on universal principles. New concepts often have a much wider validity than in the ﬁeld in which they are discovered, and methods developed in one ﬁeld are sometimes very useful in another. Hence, theoretical physics is characterized by unity in diversity. The research program of the DRSTP is organized according to two themes:

Theme 1: Particle physics, cosmology, quantum gravity and string theory. Theme 2: Quantum matter, quantum information, soft condensed matter and biophysics. 8 DRSTP Annual Report 2012

The speciﬁc content of the research program depends on the responsible project leaders, on their creativity as well as their success in acquiring research funding from their home university, from the Dutch research councils of NWO, or from international sources such as European Union programs.

The research output of DRSTP members presented in this Annual Report is presented according to the two mentioned research themes. The mission statement of the DRSTP can be found in Appendix A. 2 The DRSTP in 2012

On 31 December 2012, 103 PhD students were aﬃliated to the DRSTP, 60 tenured and 71 non-tenured staﬀ (postdocs). The research output led to 22 PhD dissertations and 318 academic publications.

This chapter describes two highlights of research in theoretical physics, presented from the personal point of view of members of the Research School who have been actively involved in them. One describes novel results in non-equilibrium physics of strongly coupled systems. This work belongs to theme 1 of the School and the contribution was written by Dr. Michal P. Heller. A second highlight belongs to theme 2 and deals with a new approach to quantum computation. This contribution was written by Professor Carlo W.J. Beenakker.

Hydrodynamics at its limits (Dr. Michal P. Heller, University of Amsterdam)

One of the most active current trends in theoretical high energy physics are investig- ations of a large class of strongly interacting models using holographic methods. In this novel approach certain strongly coupled collective states of matter are recognized as black hole geometries in one dimension more. This enables the use of general relativity techniques to describe a wide class of quantum strong coupling phenomena (see [1,2] for a review). A prototypical example of such a holographic application, and perhaps the most suc- cessful one in terms of phenomenological impact, is modeling quark-gluon plasma in its strongly coupled regime using the dual, gravitational description. Quark-gluon plasma is a collective state of matter governed by the strong nuclear force, in which quarks and gluons are not conﬁned within individual protons (or other hadrons), as in normal conditions. Predicted soon after the discovery of the theory of the strong interactions in the 1970’s, quark-gluon plasma has been realized experimentally in relativistic heavy ion collisions only at the beginning of the 21st century, ﬁrst at RHIC and later at LHC (see [3] for the introduction to the subject). Although static properties of quark-gluon plasma such as the equation of state, can be predicted ab initio using lattice gauge theory calculations on supercomputers, experimental conditions at RHIC and LHC necessarily create a time-dependent system. Providing estimates of dynamical properties of quark-gluon plasma in its strongly coupled regime is what made the holographic correspondence a widely appreciated tool among high energy physicists working on relativistic heavy ion collisions. 16 DRSTP Annual Report 2012

In particular, the hallmark of experimentally created quark-gluon plasma (as a strongly coupled liquid) is the value of its shear viscosity which is of the order of its holographic estimates given by the famous expression (in natural units) [3].

1 shear viscosity = O × entropy density (3.1) 4π

Heavy ion collisions do not create directly the quark-gluon plasma - they are instead a highly non-equilibrium processes in which quark-gluon plasma emerges once the system settles down close enough to equilibrium. An important phenomenological as- sertion is that the process of quark-gluon plasma creation happens over a very small time scale, of order of the temperature inverse at the moment of applicability of hydrodynamics [4]. A natural question for holographic techniques was whether such short equilibration times can be achieved in strongly coupled models, since weakly coupled models superficially fail to reproduce this feature [5]. The calculation of shear viscosity (Equation (3.1)) in 2001 involved small perturbations of a static black hole and as such was done analytically [6]. However, quark-gluon plasma creation, which intuitively can be understood as black hole formation in the dual picture, is a process necessarily involving large disturbances and hence requiring numerical treatment. Such situations became manageable only recently with the arrival of numerical relativity techniques applicable to black hole spacetimes relevant for holographic applications, and are the subject of the research program outlined below. The first question that needed to be addressed is whether the phenomenological as- sertion of fast equilibration in heavy ion collisions is actually microscopically realized in any other physical system, in this context in strongly coupled theories with holographic duals. A series of pioneering works by other authors indicated that this is indeed the case based on the study of a few examples of non-equilibrium states [7-9]. Subsequently, the papers [A, B] starting the outlined research program used a novel approach to cover a much bigger space of non-equilibrium evolutions and found no exceptions from fast equilibration (see Figure 3.1). Given this evidence, the most interesting question became understanding the state of the system at the brink of hydrodynamics becoming a good language to describe its subsequent evolution. Before describing these novel developments, it will be useful to pause and remind the reader about the modes that exist in holographic quark-gluon plasma when deviations from equilibrium are small in amplitude. Typically, such excitations are exponentially dampened over a time scale set by the inverse of the temperature (the so-called quasinormal modes)with the exceptions of modes which carry very low momentum and 3. Scientific highlights 17 have very small frequency [10]. The damping of those modes is very slow and if one waits longer than the temperature inverse, it will be only those modes that will persist in the system. These are precisely hydrodynamic modes and the process described above is a small amplitude analogue of distortions relevant for the plasma creation.

Figure 3.1: Histogram of equilibration times for holographic quark-gluon plasma based on sampling 1000 diﬀerent initial conditions (taken from [B]). Note that equilibration happens there at most over a time scale set by the temperature inverse.

From this perspective, it seems natural to define the time of applicability of hydrodynamics as a time scale over which the quasinormal modes, or rather their nonlinear analogues, significantly decay. This approach does not a priori constrain the size of the gradients present in the system at the moment of the applicability of hydrodynamics, as long as hydrodynamics predicts correctly its subsequent evolution. A partial indication for this idea came from [B], were it was found and stressed that one- dimensionally expanding matter can be significantly anisotropic, yet well-described by hydrodynamics (see Figure 3.2). This development, together with independent observations of this phenomenon in [8] and [9], led to coining a new word for the applicability of hydrodynamics which is “hydrodynamization”. This distinguishes it from thermalization, in which case the system is expected to be roughly isotropic and the gradients are expected to be bounded. 18 DRSTP Annual Report 2012

The new insight of “hydrodynamization” led to another development, which is understanding the character of hydrodynamics as an effective field theory. From the modern perspective, dynamical fields in hydrodynamics are local velocity and temperature (roughly speaking the modes whose dampening is the slowest) and the theory is formulated in the gradient expansion. Viscous Navier-Stokes equations (or in the holographic context their relativistic counterpart) are then just the lowest physically interesting truncation of a more complicated theory. The question that was addressed in [C] was whether this more complicated theory can provide a finite answer if treated exactly. Figure 3.3, taken from [C], provides evidence that in hydrodynamics this is not the case and hydrodynamics is an asymptotic series. In simple terms, hydrodynamics cannot give the full answer (cannot converge) as no matter how long one waits, there are always exponentially small but finite remnants of other degrees of freedom that are not captured by it. This observation was further quantified in [C] by uncovering information about quasinormal modes from the large order behavior of the hydrodynamic series in a very close analogy with instantons and perturbative expansions in quantum field theories.

Figure 3.2: Spacetime evolution of plasma expanding in one dimension is necessarily associated with pressure anisotropy between longitudinal and transverse directions. If that plasma was in equilibrium, its pressure would be equal to one third its energy density. The plot, based on the results from [A], shows time evolution of pressure anisotropy (grey solid curve) and its prediction by viscous hydrodynamic (red dotted curve). One can clearly see that hydrodynamics becomes applicable very quickly, yet the system is highly anisotropic. 3. Scientiﬁc highlights 19

Adopting an operational point of view, one is inevitably led to colliding holographically lumps of matter moving at relativistic speeds, as was considered in [9] and more recently in [D] (see Figure 3.4).

Figure 3.3: Coeﬃcients of subsequent contributions to the energy density from hydrodynamics with no gradients included (n=2) up to terms carrying 240 gradients (n=242). Contribution from Equation (3.1) corresponds to n=3. The plot is taken from [C] and provides the evidence that hydrodynamics is an asymptotic series..

One of the biggest problems in bridging the gap between holographic models of far- from-equilibrium physics and phenomenology is deciding which non-equilibrium states are the closest to teach us something about the experimental conditions in heavy ion collisions. Adopting an operational point of view, one is inevitably led to colliding holographically lumps of matter moving at relativistic speeds, as was considered in [9] and more recently in [D]. Both models correspond to collisions of infinite sheets of matter with no internal structure. However, in experiment such internal structure is important as colliding objects have a fine structure (consist of nucleons) [11]. The resulting inhomogeneities in the collective medium lead to large gradients and early applicability of hydrodynamics in this regime needs to be re-examined. The holographic evidence for fast hydrodynamization would suggest that this happens, but a precise model calculation showing this explicitly is still lacking and would be a natural continuation of this research agenda. In summary, rapid development of numerical techniques in the holographic context has opened a window on fascinating non-equilibrium physics of collective media at strong coupling. The most important phenomenological lesson seems to be a distinc- tion between the applicability of hydrodynamics and thermalization. This provides justification for using hydrodynamics in the presence of large gradients, as long as far-from-equilibrium degrees of freedom have relaxed. On more theoretical ground, it was fascinating to see that hydrodynamics is a divergent series whose large-order behavior is governed by degrees of freedom outside the hydrodynamic approximation. Both lessons seem to be general and extend outside the phenomenology of relativistic heavy ion collisions and holographic models.

Design of a building block for a topological quantum computer (Professor Carlo W.J. Beenakker, Leiden University)

Majorana fermions (midgap states) at the end points of a superconducting wire have non-Abelian statistics: when these particles are moved around each other (braided), the final state depends on the order of the performed exchange. The unitary matrices describing these exchange operations can be the building blocks for a quantum computation. Because only the order of the exchanges matters, and not their timing, the operation has an intrinsic “topological” robustness. Existing braiding proposals rely on gate electrodes to control the tunneling at the wire junction. This is problematic in a superconductor, which screens the electric field. We have developed a method to exchange Majorana fermions by control over magnetic rather than electric fields. The key ingredient of our method is the remarkable fact that the Coulomb interaction of Majorana fermions can be switched on and off with exponential accuracy by varying the magnetic flux through a split Josephson junction. See Figure 3.5. In earlier work we had showed how magnetic flux control can be used to read out and rotate the topological qubit encoded in Majorana fermions. The braiding operation was the missing building block for a topological quantum computer.

This chapter provides an overview of the educational program and of the PhD degrees granted in 2012. Research projects of current PhD students and data on their sci- entiﬁc and educational activities in 2012 are given.

The DRSTP oﬀers a joint program of graduate education leading to a PhD. The educational program is based in part on the regular advanced courses, seminars and topical courses oﬀered at the participating universities. The DRSTP organizes at least two postgraduate schools every year. Furthermore, students can gain international experience by attending (international) workshops or summer schools and, in certain cases, by making extended research visits abroad. The Governing Board is advised on educational matters by the Educational Board. Regular advanced courses at the universities are published in a nationwide survey at the beginning of each academic year.

The Governing Board of the DRSTP decides on admission of individual PhD students and monitors their progress. An extended description of the selection and supervision procedure is presented in Appendix B.

Beugeling, W. (UU) thesis title: Topological states of matter in two-dimensional fermionic systems advisor: Prof. C. Morais Smith date: 19 September 2012 present position: postdoctoral fellow, Max Planck Institute for the Physics of Com- plex Systems, Dresden, Germany

Topological states of matter in two-dimensional systems are characterised by the different properties of the edges and the bulk of the system: The edges conduct electrical current while the bulk is insulating. The first well-known example is the quantum Hall effect, which is induced by a perpendicular magnetic field that generates chiral edge channels along which the current propagates. Each channel contributes one quantum to the Hall conductivity. Due to the chirality, i.e., all currents propagate in 4. PhD program 25 the same direction, backscattering due to impurities is absent, and the Hall conductivity carried by the edge states is therefore protected from perturbations. Another example is the quantum spin Hall effect, induced by intrinsic spin-orbit coupling in absence of a magnetic field. There the edge states are helical, i.e., spin up and down currents propagate oppositely. In this case, the spin Hall conductivity is quantized, and it is protected by time-reversal symmetry from backscattering due to impurities. In Chapter 2 of the thesis, I discuss the combined effect of the magnetic field and intrinsic spin-orbit coupling. In addition, I discuss the influence of the Rashba spin-orbit coupling and of the Zeeman effect. In particular, I show that in absence of magnetic impurities, a weaker form of the quantum spin Hall state persists in the presence of a magnetic field. In addition, I show that the intrinsic spin-orbit coupling and the Zeeman effect act similarly in the low-flux limit. I furthermore analyse the phase transitions induced by intrinsic spin-orbit coupling at a fixed magnetic field, thereby explaining the change of the Hall and spin Hall conductivities at the transition. I also study the subtle interplay between the effects of the different terms in the Hamiltonian. In Chapter 3, I investigate an effective model for HgTe quantum wells doped with Mn ions. Without doping, HgTe quantum wells may exhibit the quantum spin Hall effect, depending on the thickness of the well. The doping with Mn ions modifies the behaviour of the system in two ways: First, the quantum spin Hall gap is reduced in size, and secondly, the system becomes paramagnetic. The latter effect causes a bending of the Landau levels, which is responsible for reentrant behaviour of the (spin) Hall conductivity. I investigate the different types of reentrant behaviour, and I estimate the experimental resolvability of this effect. In Chapter 4, I present a framework to describe the fractional quantum Hall effect in systems with multiple internal degrees of freedom, e.g., spin or pseudospin. This framework describes the so-called flux attachment in terms of a Chern-Simons theory in Hamiltonian form, proposed earlier for systems without internal degrees of freedom. Here, I show a generalization of these results, by replacing the number of attached flux quanta by a matrix. In particular, the plasma analogy proposed by Laughlin still applies, and Kohns theorem remains valid. I also show that the results remain valid when the flux-attachment matrix is singular.

Boon, N.J.H. (UU) thesis title: Electrostatics in ionic solution : work and energy, charge regulation, and inhomogeneous surfaces advisor: Prof. H. van Beijeren co-advisor: Dr. R.H.H.G. van Roij date: 31 January 2012 present position: postdoctoral fellow, Institute for Theoretical Physics, Utrecht Uni- versity, the Netherlands

This thesis concerns the electrostatic properties of charged objects that are immersed into an ionic solvent, for example water with dissolved salt. Typically, the ions inside such a solvent form layers of countercharge close to the charged objects, causing 26 DRSTP Annual Report 2012

‘screening’ of the charges. By employing Density Functional Theory (DFT) one is able integrate out the degrees of freedom of the ions and find relations that describe the effective electrostatic properties of the charged objects. One finds that for a large parameter regime the electrostatic potential everywhere in the solvent should satisfy the well established Poisson-Boltzmann equation. We study the electrostatic capacity of porous electrodes in salt water, and derive a method to reversibly extract electric energy from salinity gradients that occur for example at an estuary where sea- and river water meet. However, in the main part of this thesis we consider charged colloidal particles, and study the effect of internal porosity as well as heterogeneities in the surface-charge density (patchy particles) on colloid-colloid interactions. In a far- field analysis we derive equations that describe these interactions for particles with nonvanishing multipole moments, for example ‘Janus’ colloids with a strong dipole component. If such particles locally have a high surface charge density, then the nonlinear dependence of the counterion density on the local charge density leads to a generalisation of charge renormalisation from purely monopolar to dipolar, quad- rupolar, etc., including ‘mode couplings’. In a more detailed approach, which turns out to be important for colloidal particles at smaller distances from each other, we consider the chemical processes that lead to surface charge, and specify a parameter regime in which charging can be described by a single ‘chargeability’ parameter. As we show in this thesis, the phase diagrams we obtain within this regime have many similarities with a ‘constant surface potential’ surface model. The charging of patches on a surface is often much stronger than bulk surface, measured per area. We find a characteristic increase of the charge density close to the edges of a patch. Although the interaction energy between homogeneously charged surfaces is expected to decay exponentially within Poisson-Boltzmann theory, we find that the interactions of patched surfaces can behave totally different at distances that are smaller than the length scale that is set by the size of the patches. For the case of negatively chargeable surfaces with positively chargeable patches, we find that the net force between the surfaces can change from repulsive at larger distances to attractive at short distances. The strength of the forces and the location of the transition can be tuned with the patch size and the bulk and patch chargeability.

Budd, T.G. (UU) thesis title: Non-perturbative quantum gravity: a conformal perspective advisor: Prof. R. Loll date: 20 March 2012 present position: postdoctoral fellow, Copenhagen University, Niels Bohr Institute, Theoretical Particle Physics and Cosmology, Denmark

The construction of meaningful observables in models of quantum gravity is a highly non-trivial task, but necessary in order to study their continuum physics. In this thesis several such observables are identiﬁed in lattice models of quantum gravity. In dynamical triangulations in two dimensions with topology of the torus we have studied numerically the lengths of non-contractible loops and the moduli parametriz- 4. PhD program 27 ing the conformal structure. Good agreement is found with analytical results from Liouville gravity. Using similar methods we have studied the time evolution of the conformal structure in causal dynamical triangulations in 2+1 dimensions with spatial topology of the torus. An eﬀective model is constructed describing the outcome of the computer simulations and compared to various continuum descriptions of quantum gravity in 2+1 dimensions.

Dahlhaus, J.P. (UL) thesis title: Random-matrix theory and stroboscopic models of topological insulators and superconductors advisor: Prof. C.W.J. Beenakker date: 21 November 2012 present position: postdoctoral fellow, Department of Physics, University of Califor- nia, Berkeley, USA

Topological phases of matter are exceptional because they do not arise due to a symmetry breaking mechanism. Instead they are characterized by topological invariants – integer numbers that are insensitive to small perturbations of the Hamiltonian. As a consequence they support conducting surface states that are protected against disorder and other imperfections. Furthermore, a variety of unusual transport properties arise due to the presence of topology. In this work the interplay between topology and sample imperfections is investigated with a focus on transport phenomena. de Adelhart Toorop, R. (Nikhef) thesis title: A ﬂavour of family symmetries in a family of ﬂavour models advisor: Prof. J.-W. van Holten co-advisor: Dr. F. Bazzocchi (SISSA, Trieste, Italy) date: 21 February 2012 present position: research associate, Roland Berger Strategy Consultants, Amster- dam, the Netherlands

The Standard Model of Particle Physics has many (19) free parameters, most of which (13) are related to the masses and mixing angles of the elementary fermions (quarks and leptons). If we include neutrino masses, even 22 of the 28 parameters are related to the fermion mass sector. Although these parameters can in principle be completely random, there seems to be a lot of structure here: highly hierarchical masses for the quarks and charged leptons and very peculiar mixing angles for the neutrinos. We can use family symmetries to explain this structure. In models with family symmetry, there is not only the (gauge) symmetry between the types of particles, but also a symmetry between the diﬀerent families. In this thesis, we consider several model building applications of family symmetries. 28 DRSTP Annual Report 2012

Dibitetto, G. (RUG) thesis title: Gauged supergravities and the physics of extra dimensions advisor: Prof. E.A. Bergshoeﬀ co-advisor: Dr. D. Roest date: 1 October 2012 present position: postdoctoral fellow, Uppsala University, Sweden

This thesis analyses supergravities in various dimensions and their possible origin from compactifications of string theory. The lower-dimensional theories arising from flux compactifications are the so-called gauged supergravities. Before the gauging procedure the theory is invariant under a certain global symmetry group which is interpreted as string duality. In gauged supergravities a certain subgroup of the global symmetry is made local and the structure constants of the gauge algebra appear in the theory as deformation parameters generating a potential for the scalarfields of the theory. The gauging breaks the invariance under the duality symmetry and still the theory can be made duality covariant by promoting the deformation parameters to tensors (embedding tensor) with respect to the global symmetry. The first important point of this thesis is that physics after compactification is only sensitive to the orbits of the global symmetry group, in that gaugings lying in the same group orbit are related by duality transformations. Given a certain gauged supergravity containing non-geometric fluxes, it becomes a natural question whether there exists a duality transformation that rotates them away. Thus the classification of duality orbits becomes relevant in order to answer this question. In this thesis we give this classification for maximal and half-maximal supergravities in dimension seven and higher. In the maximal case we find that every orbit admits a geometric representative.

Emanuel, M.D. (UL) thesis title: The eﬀect of thermal ﬂuctuations on elastic instabilities of biopolymers advisor: Prof. H. Schiessel date: 4 July 2012 present position: postdoctoral fellow, Kavli Institute, Delft University of Technology (TU Delft), the Netherlands

The influence of temperature on various elastic properties of DNA is analyzed close to elastic instabilities. The buckling transition under compression is interpreted as decreasing. Under torsion a first order phase transition is described ending in an important multi-plectoneme phase that changes to a line of critical points in the infinite chain limit. 4. PhD program 29

H¨ohn,P.A. (UU) thesis title: From classical to quantum: new canonical tools for the dynamics of gravity advisor: Prof. R. Loll date: 14 May 2012 present position: postdoctoral fellow, Perimeter Institute, Waterloo, Ontario, Canada

In a gravitational context, canonical methods offer an intuitive picture of the dynamics and simplify an identification of the degrees of freedom. Nevertheless, extracting dynamical information from background independent approaches to quantum gravity is a highly non-trivial challenge. In this thesis, the conundrum of (quantum) gravitational dynamics is approached from two different directions by means of new canonical tools. This thesis is accordingly divided into two parts: In the first part, a general canonical formalism for discrete systems featuring a variational action principle is developed which is equivalent to the covariant formulation following directly from the action. This formalism can handle evolving phase spaces and is thus appropriate for describing evolving lattices. Attention will be devoted to a characterization of the constraints, symmetries and degrees of freedom appearing in such discrete systems which, in the case of evolving phase spaces, is time step dependent. The advant- age of this formalism is that it does not depend on the particular discretization and, hence, is suitable for coarse graining procedures. This formalism is applicable to discrete mechanics, lattice field theories and discrete gravity models—underlying some approaches to quantum gravity—and, furthermore, may prove useful for numerical implementations. For concreteness, these new tools are employed to formulate Regge Calculus canonically as a theory of the dynamics of discrete hypersurfaces in discrete spacetimes, thereby removing a longstanding obstacle to connecting covariant sim- plicial gravity models with canonical frameworks. This result is interesting in view of several background independent approaches to quantum gravity. In addition, perturbative expansions around symmetric background solutions of Regge Calculus are studied up to second order. Background gauge modes generically become propagating at second order as a consequence of a symmetry breaking. In the second part of this thesis, the paradigm of relational dynamics is considered. Dynamical observables in gravity are relational. Unfortunately, their construction and evaluation is notoriously difficult, especially in the quantum theory. An effective canonical framework is devised which permits to evaluate the semiclassical relational dynamics of constrained quantum systems by sidestepping technical problems associated with explicit constructions of physical Hilbert spaces. This effective approach is well-geared for addressing the concept of relational evolution in general quantum cosmological models since it (i) allows to depart from idealized relational ‘clock references’ and, instead, to employ generic degrees of freedom as imperfect relational ‘clocks’, (ii) enables one to systematically switch between different such ‘clocks’ and (iii) yields a consistent (temporally) local time evolution with transient observables so long as semiclassicality holds. These techniques are illustrated by toy models and, finally, are applied to a non-integrable cosmological model. It is argued that relational evolution 30 DRSTP Annual Report 2012 is generically only a transient and semiclassical phenomenon.

Hristov, K.P. (UU) thesis title: Lessons from the vacuum structure of 4d N=2 supergravity advisor: Prof. S.J.G. Vandoren date: 1 June 2012 present position: postdoctoral fellow, University of Milano-Bicocca, Italy

This thesis is devoted to a study of supersymmetry preserving background solutions of N=2 supergravity in 4 dimensions. These models include arbitrary electric gaugings in the vector- and hypermultiplet sectors introduced in the beginning of the thesis. The main contents are divided into three major parts. In part 1 we consider vacua that can be fully analyzed by requiring preserved supersymmetry. We determine and analyze maximally supersymmetric configurations, preserving eight supercharges. We present several examples of such solutions and connect some of them to vacuum solutions of flux compactifications in string theory. We also provide a consistent truncation of the gauged theory based on integrating out massive supermultiplets of the gauged theory. The second part is devoted to the topic of supersymmetric black holes. These can be asymptotically flat or asymptotically AdS, and we analyze both cases in detail. We construct BPS black hole solutions in Minkowski space with charged hypermultiplets. We find solutions with vanishing scalar hair that resemble already known black holes, while the genuinely new solutions with hair that we find contain ghost modes. We also elaborate further on the static supersymmetric AdS black holes found in arXiv:0911.4926, investigating thoroughly the BPS constraints for spherical symmetry in N = 2 gauged supergravity. We find Killing spinors that preserve two of the original eight supercharges and investigate the conditions for genuine black holes free of naked singularities. The existence of a horizon is intimately related with the requirement that the scalars are not constant, but given in terms of harmonic functions in analogy to the attractor flow in ungauged supergravity. The third major topic of this thesis is BPS bounds, where we discuss asymptotically Minkowski and AdS solutions in full generality. We concentrate on asymptotically anti-de Sit- ter (AdS) spacetimes, and find that there exist two disconnected BPS ground states of the theory, depending on the presence of magnetic charge. Each of these ground states comes with a different superalgebra and a different BPS bound, which we derive. As a byproduct, we also demonstrate how the supersymmetry algebra has a built-in holographic renormalization method to define finite conserved charges. We derive the general form of the charges for all asymptotically flat, anti-de Sitter, and magnetic anti-de Sitter spacetimes. Some particular black hole examples from part 2 are considered to explicitly demonstrate how AdS and mAdS masses differ when solutions with non-trivial scalar profiles are considered. 4.

Kadosh, A. (RUG) thesis title: The ﬂavor of symmetries in a warped extra dimension and a ‘slinkyvolving’ view of creation advisor: Prof. E. Pallante date: 23 April 2012 present position: unknown

The long term aim of the research performed in this thesis is to establish a new unified framework in the context of Warped Extra Dimensions (WED), which will enable the construction of phenomenological models with concrete experimental signatures for both particle physics and cosmology. In order to achieve these goals we have pursued a multidisciplinary research focused on two directions. The first is the construction and thorough phenomenological study of a reliable flavor physics model in WED with an additional A4 bulk flavor symmetry, including both the quark and lepton sectors and their implications in flavor and neutrino physics. The second is the establishment of time dependent gravitating domain wall (DW) configurations in 4+1 space-time dimensions (5D), the most elegant dynamical realization of realistic cosmological brane world scenarios. The ‘warped’ A4 model provides a simultaneous explanation of the gauge and flavor hierarchy problems, the smallness of neutrino masses and the nature of neutrino mixing. The latter model is shown to satisfy the most important constraints coming from precision electroweak and flavor physics data. In particular, we analyze the new physics contributions to the Zbb vertex, the neutron EDM, Kaon charge-parity (CP) violating observables and the b → s + γ decay. In the context of DW brane cosmology we introduce the notion of ‘slinky evolution’ of DW configurations and find a very simple non factorizable time dependent DW solution in (5D) admitting a ‘Slinkyvolving’ time evolution, implying an appealing interpretation for the resulting 4D cosmology. We then discuss the problems associated with this solution.

Klauser, A.M. (UvA) thesis title: Adjacent spin operator correlations in the Heisenberg spin chain advisors: Prof. J. van den Brink (Dresden); Prof. C.J.M. Schoutens co-advisor: Dr. J.-S. Caux date: 5 April 2012 present position: analyst, Magnetic Resonance Imaging (MRI), Image Analysis Center (IAC), Radiology Department, Vrije Universiteit Amsterdam Medical Center (VUMC), Amsterdam, the Netherlands

Throughout the thesis, we study the correlations of adjacent spin pairs in the onedi- mensional S = 1/2 Heisenberg spin chain. The Heisenberg model is made of spin-1/2, intrinsic quantum magnetic moments of which the measured value is either up |↑ or down |↓. The spins are arranged in a row and every spin undergoes with its two nearest neighbors an interaction which tends to align (ferromagnetic model) or anti-align (antiferromagnetic model) the spins. In 32 DRSTP Annual Report 2012 the Heisenberg model, this interaction between two spins is isotropic, i.e. the same in the three spatial directions. We determine the correlation of adjacent spin pairs in the antiferromagnetic Heisen- berg spin chain at zero temperature. This result can be interpreted as the probability to measure the same values of an adjacent spin pair at two different positions along the spin chain and within a given time interval. Such one-dimensional magnetic systems exist in nature and can be realized by crystal insulator compounds. Therefore arises the question of measuring the adjacent spin correlations with a realistic experiment. We explain how using x-rays in a precise range of frequencies, a scattering process, namely the K-edge Resonant Inelastic X-ray Scattering, occurs and that the measurement of the out-coming x-ray is proportional to the spin-exchange, one adjacent spin operator correlation function. In order to solve the dynamics of the spin chain, its eigenstates are constructed with the coordinate Bethe Ansatz, yielding an expression for the energy and the momentum of each state. We recall then the Bethe equations in the Orbach parametrization and the Bethe-Takahashi equations. A classification of the fundamental excitations above the groundstate is made and the densities of states of the so-defined excitation types are calculated for a finite spin chain. In order to determine adjacent spin operator correlation functions, a short introduction to the algebraic Bethe Ansatz is given and we remind the reader of the essential algebraic expressions that allow one to compute the form factors of two adjacent spin operators: the algebraic form of an eigenstate, the representation of local spin operators, the norm of a state and the scalar product of two states. On this basis, determin- − − z z ant formula for the form factor of the operators Sj Sj+1 and Sj Sj+1 are determined and these last results allow us to express the adjacent spin operator correlation functions S−−++(q, ω),S4z(q, ω) and Sexch.(q, ω) for a finite spin chain. Additionally, we calculate the sum rules for the three corresponding correlation functions: the integ- rated intensities and the first frequency moments. The expressions are then evaluated numerically for the interpretations of the results and to determine the contribution of each excitation type previously classified. Within the extensive analysis of the signal made for S−−++(q, ω),S4z(q, ω) correlation functions in several external magnetic fields, we find a large contribution of the 4-spinon states in the S4z(q, ω) at zero magnetic field. In addition, in regions of momentum- energy, the signal can be clearly attributed to 4-spinon excitations and distinguished from the 2-spinon signal. The numerical evaluation of Sexch.(q, ω) provides the response function of K-edge Resonant Inelastic X-ray Scattering measurement and these results are compared with Szz(q, ω), the response function of the inelastic neutron scattering that is the commonly used method to probe the the dynamics of the spin chain. The spinexchange correlation function reveals the same shape as the single spin correlation function and is made of almost only 2-spinon signal. At low energy, however, the response vanishes and makes the comparison with low energy effective results almost impossible. The explicit and detailed content presented in the thesis allows one to construct, in principle, any other adjacent spin operator correlation function. 4. PhD program 33

Lucassen, M.E. (UU) thesis title: Coupling between current and dynamic magnetization: from domain walls to spin waves advisor: Prof. H.T.C. Stoof co-advisor: Dr. R.A. Duine date: 16 May 2012 present position: young professional test and quality, IT, Sogeti, Vianen, the Nether- lands

So far, we have derived some general expressions for domain-wall motion and the spin motive force. We have seen that the parameter plays a large role in both subjects. In all chapters of this thesis, there is an emphasis on the determination of this parameter. We also know how to incorporate thermal fluctuations for rigid domain walls, as shown above. In Chapter 2, we study a different kind of fluctuations: shot noise. This noise is caused by the fact that an electric current consists of electrons, and therefore has fluctuations. In the process, we also compute transmission and reflection coefficients for a rigid domain wall, and from them the linear momentum transfer. More work on fluctuations is done in Chapter 3. Here, we consider a (extrinsically pinned) rigid domain wall under the influence of thermal fluctuations that induces a current via spin motive force. We compute how the resulting noise in the current is related to the β parameter. In Chapter 4 we look into in more detail into the spin motive forces from field driven domain walls. Using micro magnetic simulations, we compute the spin motive force due to vortex domain walls explicitly. As mentioned before, this gives qualitatively different results than for a rigid domain wall. The final subject in Chapter 5 is the application of the general expression for spin motive forces to magnons. Although this might seem to be unrelated to domain-wall motion, this calculation allows us to relate the β parameter to macroscopic transport coefficients.

Malamos, I.E. (RU) thesis title: Reduction of one and two loop amplitudes at the integrand level advisors: Prof. R.H.P. Kleiss; Prof. C.G. Papadopoulos; Prof. G.R. Pittau date: 2 July 2012 present position: postdoctoral fellow, University of Valencia, Spain

In order to answer fundamental questions in science, such as what is our universe made of or where does the mass of the particles comes from, physicists build colliders. The Large Hadron Collider (LHC) is such an example, where protons are accelerated at very high energies and then collide with each other to produce other particles in conditions closer to the big bang. The procedure that follows resembles searching for needles in a haystack. Data that 34 DRSTP Annual Report 2012 are produced include a lot of background signals that have to be understood and removed for some few new events to pop up and give something new. It is clear that the higher the energy becomes, the best accuracy is needed in the knowledge of these background processes. Once new particles have been discovered, they become the new backgrounds for future colliders. The way to improve our knowledge and accuracy is to calculate higher order corrections in perturbation theory. Then, one can compare these very precise theoretical results with the experimental data and understand the output of the experiments. The thesis deals with new methods to perform higher order calculations. It has as a starting point the so called OPP method that performs reduction of one loop Amp- litudes at the Integrand level. The method is described in detail, both in four and d dimensions. In the latter case, extra terms have to be included that are called Ra- tional terms. In the framework used in the thesis, they are split in two pieces R1 and R2 respectively. The R1 terms can be calculated together with the four dimensional part of the Amplitude while for the R2 terms a different approach has to be used. More specifically, new vertices have to be used, in the spirit of counterterms, and an extra tree level, calculation using these extra vertices, has to be performed. Feynman rules for these new vertices have been produced and listed in the thesis. The calculations have been performed in more than one gauges (’t Hooft- Feynman gauge, Rξ gauge and Unitary gauge) and gauge invariant properties have been also studied. Once the one-loop program was completed, there were efforts to extend Reduction at the Integrand level to two-loop Amplitudes. In the thesis it is shown that this is always possible to be done. Scalar two-loop integrals are considered and it is shown, how and when can they be reduced in the spirit of Unitarity methods in different dimensions. The degree of polynomial coefficients that solve the reduction problem is also given in different dimensions. If one wants to find a minimal base for two loop Integrals, one has to include on top IBP identities. At the end of the thesis, it is shortly described how one can include such identities in the same footing with the OPP method.

Mink, M.P. (UU) thesis title: Pseudospin pairing and transport in atomic Fermi gases and bilayer systems advisor: Prof. H.T.C. Stoof co-advisor: Dr. R.A. Duine date: 12 September 2012 present position: mathematical consultant, Laboratory for Industrial Mathematics (LIME bv), Eindhoven, the Netherlands

In this thesis we consider the behavior of the drag conductivity close to exciton condensation in bilayer systems and close to the superﬂuid transition in cold Fermi gases. In chapter 2 we calculate the transition temperature for exciton condensation in double-layer graphene, showing that the remote bands can play a supporting role in this transition. In chapter 3 we consider a topological insulator thin ﬁlm and calculate the behavior of the drag resistivity close to the transition temperature. We 4. PhD program 35

find a strong enhancement which can be used as a precursor for the transition. In chapter 4 we discuss an ultracold Fermi gas close to the superconducting transition and compare two different methods to obtain the drag resistivity, each taking into account a different phenomenon which affects the drag resistivity close to the transition. Finally, in chapter 5, we present a uniform theoretical framework to determine the drag resistivity in all experimental systems considered in this thesis.

Mossel, J.J. (UvA) thesis title: Quantum integrable models out of equilibrium advisor: Prof. J.-S. Caux date: 13 September 2012 present position: asset management, Goldman Sachs, London, UK

In this thesis quantum integrable models out of equilibrium are studied. We assume that the many-body system is isolated, so that the dynamics are not dictated by the environment and is therefore purely unitary. Until a decade ago isolated quantum many-body systems out of equilibrium were mainly hypothetical. Now this has become a reality with the recent advances in the experiments with ultra cold atomic gases. The coherence times of cold atomic gases are sufficiently large so that they can be considered to be isolated. These gases are highly controllable; both weakly and strongly interacting many-body systems can be realized. Moreover, one can superim- pose an external potential, thereby reducing the dimensionality and/or creating an optical lattice. This makes it not only possible to create various systems, but also to prepare these systems in specific states. A popular way of bringing a system out of equilibrium is to perform a so-called quantum quench: first the system is prepared in its ground state, and then subjected to a sudden change (quench) of one of the Hamiltonian parameters (e.g. switching off an external field, changing the interaction strength, etc.). As result of such a quench the system will not be in an eigenstate and (complicated) non-equilibrium dynamics will follow. These experiments raised the interesting question under which conditions an isolated quantum many-body system will thermalize; in other words, if a systems relaxes after it was initially brought out of equilibrium, can it be described by a statistical ensemble?

Niessen, A.I.M. (RU) (CUM LAUDE) thesis title: Improving predictions for SUSY cross sections advisor: Prof. R.H.P. Kleiss date: 8 November 2012 present position: advisor, Andersson Elﬀers Felix, Utrecht, the Netherlands

As far as we know, the building blocks of the universe are described by a theory called the Standard Model. It describes all the particles we have observed: quarks, leptons, force particles, and the recently discovered Higgs boson. We have also observed the corresponding antiparticles, and the theory passes all the tests it has been put to. Except for one. Astrophysicists have observed something called ‘dark matter’, but 36 DRSTP Annual Report 2012 according to the Standard Model there is no invisible particle that could possibly explain this dark matter. So it seems that the Standard Model is not complete and we have to look for a better theory. One possibility is supersymmetry, which high energy physicists lovingly call SUSY. This theory predicts that every particle we know has a partner particle. These supersymmetric partners are quite similar to the corresponding Standard Model particles, except that they have a different spin and mass. If supersymmetric particles exist, we want to find them. This can best be achieved by making them ourselves in a particle accelerator. The most powerful particle accelerator today is the Large Hadron Collider (LHC) at CERN. To understand the measurements at the LHC, we have to compare them to theoretical predictions. In particular, we need to know how many supersymmetric particles to expect or the cross section. At leading order, the calculation for the cross section is fairly straightforward. Un- fortunately, nothing prevents nature from temporarily making more particles in the process, giving rise to higher-order corrections. We can handle the calculation up to next-to-leading order accuracy, but we need a higher precision to compare the results to the LHC data. That is where resummation comes into play. For heavy particles, the most important higher-order contribution comes from a specific type of diagram with additional gluons. These diagrams are relatively simple and have the unique property that we can combine parts of these very important diagrams in our calculation. As a result, we can calculate the most important contributions of diagrams with one, two, three, up to infinitely many extra gluons, all at once. This way of collecting these contributions is called resummation. Resummation is a different way of organizing the calculation and improves the result. This thesis is about resummation for the production of squarks and gluinos. The improved calculation yields a higher cross section and smaller uncertainties than the previous next-to-leading order calculation. The results are currently used at the LHC to compare the measurements to the theory.

Romers, J.C. (UvA) thesis title: Topological order in condensed matter physics advisors: Prof. F.A. Bais; Prof. C.J.M Schoutens date: 25 September 2012 present position: postdoctoral fellow, Peierls Lab, Oxford University, UK

We study systems that exhibit topological order, a novel type of order in condensed matter physics in which diﬀerent phases of matter cannot be distinguished by a local order parameter. Two examples are studied in particular: a lattice model that realizes a Discrete Gauge Theory and the fractional quantum Hall state at ﬁlling fraction 5/2. In the former model, we study phase transitions that arise due to the condensation of quasiparticles. In the latter model, we construct wave functions for spinful excitations that are a particular incarnation of half-skyrmions. 4. PhD program 37

Sousa S´anchez, K. (UL) thesis title: Consistent supersymmetric decoupling in cosmology advisor: Prof. A. Ach´ucarro date: 20 June 2012 present position: University of the Basque Country (UPV/EHU), Theoretical Physics and History of Science, Spain

The present work discusses several problems related to the stability of ground states with broken supersymmetry in supergravity, and to the existence and stability of cosmic strings in various supersymmetric models. In particular we study the necessary conditions to truncate consistently a sector of an N = 1 supergravity theory while preserving supersymmetry, and on those models where these conditions are met we discuss how the breaking of supersymmetry in the light sector affects the stability of the truncated fields. In this thesis we also present a new type of supersymmetric cosmic string solutions in N = 2 supergravity. The corresponding model admits a family of cosmic string solutions with the same energy but different core radius. We study the stability of these strings against perturbations in a cosmological context, where the zero mode connecting different solutions within a family could be excited, leading to the spread of the magnetic flux and the disappearence of the string.

Swaving, A.C. (UU) thesis title: Spin transport and dynamics in antiferromagnetic metals and magnetic insulators advisor: Prof. H.T.C. Stoof co-advisor: Dr. R.A. Duine date: 2 March 2012 present position: Commerzbank

It is demonstrated that in an antiferromagnetic metal a steady-state transport current generates a current-induced out-of-plane spin density, resulting in torques on the magnetization. This spin density is parameterized by a velocity that is proportional to the current. The generalization of the non-linear sigma model equation of motion for antiferromagnetic magnetization dynamics in an antiferromagnetic metal in the presence of a transport current is presented. From this equation of motion a current-induced shift of the spin-wave dispersion is found, as well as current-induced torques that lead to current-driven antiferromagnetic domain wall motion. A key finding is that the form of the current-induced spin density, expressed in terms of the Néèlvector is similar to the current-induced spin density in ferromagnets with the Néèlvector replaced by the magnetization direction. The velocity that characterizes the efficiency of the coupling between current and magnetization is calculated, using linear-response theory in the Boltzmann transport regime. In the absence of dissipation, current-driven antiferromagnetic domain walls are found to move with this characteristic velocity. When magnetization damping is included, the domain wall moves a finite amount and then stops, similar to the intrinsic pinning of current-driven ferromagnetic do- 38 DRSTP Annual Report 2012 main walls. Like in the latter case, including dissipative coupling or non-adiabatic effects between current and magnetization removes this intrinsic pinning. In magnetic insulators there is no transport of electronic charge. Still, there can be transport of spin in the form of spin waves, or, in their quantized form, magnons. Spin transport, carried by quasi-equilibrium magnons, in a magnetic insulator within a Boltzmann transport framework is considered. The spin resistivity of quasi-equilibrium magnons is found to be strongly reduced in comparison with equilibrium magnons, a property that may be useful in designing magnon spintronics applications. The contribution of magnon interactions to their resistivity has been studied for the reason that these dominate in the materials that are experimentally relevant, such as yttrium-iron- garnet (YIG). Firstly, the spin resistivity of a magnon gas using the simplest model, the Heisenberg model, is used. The investigation of material-specific models, in particular for YIG, is then presented. Despite the simplified model, the main qualitative result, the reduction of spin resistivity as a result of enhancing the magnon number by pumping, remains valid. This is because it only depends on the bosonic nature of the magnon excitations that leads to enhanced scattering into states that are already occupied. van den Oord, G.W.J.M. (RU) thesis title: Recursion, Monte Carlo, and vector boson scattering at hadron colliders advisors: Prof. R.H.P. Kleiss; Prof. S.C.M. Bentvelsen date: 15 November 2012 present position: consultant/scientific software engineer, Alten PTS, Capelle a/d IJs- sel, the Netherlands

The aim of this thesis was to probe the Higgs sector in a model-independent way by studying longitudinally polarized weak gauge boson scattering. These processes are sensitive to the peculiar structure of the Higgs-gauge couplings, and the required cancellation of diverging terms within their amplitudes heavily constrain the Higgs sector. We have considered various nonstandard Higgs scenarios, including anomalous gauge couplings and extra-dimensional Higgsless models, and constructed the signatures in the W-boson scattering channel at the Large Hadron Collider by Monte Carlo simulation. To obtain these results, we have developed a complete matrix element Monte Carlo program based on the recursive calculation of scattering amplitudes. This iterat- ive method was extended to include Majorana fermions, and includes QCD in the colour-flow decomposition. For the multi-particle phase space generation we have adopted a similar method by recursively generating kinematic channels. Finally, we have simulated the full signal and dominant backgrounds - in particular top quark pair production - and performed a cut-based analysis on our Monte Carlo data at the parton level. In conclusion, it proves to be useful to study W-boson scattering at and above the Higgs threshold, even now a light, standard model Higgs-like particle has been discovered. To obtain a clear understanding of the symmetry-breaking sector of the 4. PhD program 39 standard model, longitudinally polarised weak gauge bosons remain a promising channel, complementary to the direct observation of Higgs decays. van der Aalst, T.A.F. (UL) thesis title: Conformal invariance and microscopic sensitivity in cosmic inflation advisor: Prof. A. Achúcarro co-advisor: Dr. K.E. Schalm date: 19 December 2012 present position: quantitative analyst/advisor in Financial Risk Management, KPMG, Amstelveen, the Netherlands

Phenomenologically, cosmic inflation is a satisfying and well-tested description of the physics of the very early universe. During this epoch, the universe was dominated by high energy phenomena that can only be truly understood in a quantum gravity theory such as string theory. In this thesis we show that the embedding of inflation in a string theoretic framework is very sensitive to the details of the theory. We consider both the low energy supergravity limit as well as a worldsheet set-up. Moreover, we investigate the constraints imposed by supersymmetry and conformal symmetry. Conformal symmetry is important both in the worldsheet theory as well as in a holographic description of inflation. In the latter case we investigate the imprints of conformal invariance on the (observable) statistical correlations in the cosmic mi- crowave background radiation. van Driel, H.J. (UU) thesis title: Spin transport in Bose gases advisor: Prof. H.T.C. Stoof co-advisor: Dr. R.A. Duine date: 12 December 2012 present position: unknown

In this thesis, we show that in a rotating two-component Bose mixture, the spin drag between the two different spin species shows a Hall effect. This spin drag Hall effect can be observed experimentally by studying the out-of-phase dipole mode of the mixture. We determine the damping of this mode due to spin drag as a function of temperature. We find that due to Bose stimulation there is a strong enhancement of the damping for temperatures close to the critical temperature for Bose-Einstein condensation. We also show the difference between spin drag in Bose gases, Fermi gases and Bose-Fermi mixtures. Furthermore, we investigate coupled spin and heat transport in Bose gases, and calculate the associated coefficients. Finally, we calculate the power spectrum resulting from spin current fluctuations in a Bose gas. 40 DRSTP Annual Report 2012

Objectives The Dutch Research School of Theoretical Physics (DRSTP) is a cooperation between the theoretical physics groups of six Dutch universities and of the National Institute for Subatomic Physics (Nikhef) with the following purpose: to implement a joint programme of graduate education in theoretical physics that draws upon a dynamic research environment; to maintain and strengthen research in theoretical physics from a broad unifying perspective that exploits the interrelationships between different fields of theory; to strengthen, both in research and graduate education, connections with experimental physics, and other disciplines such as mathematics, computational science, astrophysics, earth science, physical chemistry and the life sciences. The DRSTP is based on the conviction that a joint venture of all the moderately sized local theory groups, each with its own profile, offers added value for the achievement of these objectives. The DRSTP represents a sizable part of the national activity in theoretical physics, a field that has a strong tradition in the Netherlands. At present there exists no other organization that represents this field of research at the national level. The DRSTP welcomes further growth, for instance, by cooperation with institutions in neighboring countries that share these goals. Often its educational activities already attract students from neighboring countries and occasionally some of these activities are based on a close collaboration with partners abroad.

Mandate The Governing Board of the DRSTP, which consists of representatives of the partners, is responsible for undertaking any suitable initiative to further its goals. The scientific director of the DRSTP is responsible for implementing the overall policy on behalf of the Board and for coordinating the DRSTP activities. The mandate to carry out these tasks is based on an official agreement between the boards of the participating partners, as a result of which the DRSTP has been accredited by the Royal Neth- erlands Academy of Arts and Sciences (KNAW) in June of 1994 and reaccredited in 1999, 2004 and 2010. The agreement guarantees means for a six year period in terms DRSTP Annual Report 2012 148 of explicit staff commitments as well as graduate student positions. The DRSTP is assisted in its endeavor by an international Scientific Advisory Committee of distinguished scientists.

Research Theoretical physics is based on universal principles. New concepts often have a much wider validity than in the field in which they are discovered, and methods developed in one field are sometimes very useful in another. Hence theoretical physics is characterized by unity in diversity. The research fields of the DRSTP are highly diverse, ranging from the physics at the very smallest length scales to the large scale structure of space and time, and from the study of building blocks of matter to the intricacies of the many-body physics of condensed matter, be it quantum matter, soft matter or bio-matter. The methods employed in these various fields make up the universal language of theoretical physics: formalisms such as the renormalization group and quantum field theory, and various concepts of statistical, computational and mathematical physics are universally applied and establish cross-talk among the research fields. The research areas covered by the DRSTP can be grouped into the following broad and overlapping themes: Theme 1: Particle physics, cosmology, quantum gravity and string theory Theme 2: Quantum matter, quantum information, soft condensed matter and biophysics The specific content of the research programme depends on the responsible project leaders, on their creativity as well as their initiative to obtain research funding from their home universities, the Dutch research councils of NWO, or from international sources such as European Union programmes. The research programme is carried out under the responsibility of the Governing Board and the scientific director in accordance with the agreement. The Governing Board of the DRSTP safeguards the objectives of the Research School. It monitors the overall coherence and quality of the research programme. The Board discusses periodically whether the program remains on the forefront of international developments. The Scientific Advisory Committee plays an essential part in these matters. The DRSTP is also accountable to the faculties of the participating partners. There- fore it reports regularly on past and planned activities, both in research and graduate education, on the basis of information presented in its yearly reports.

Graduate programme The partners in the DRSTP oﬀer a joint program of graduate education leading to a PhD. As part of the research training, under the supervision of a member scientist of the corresponding node, the Research School guarantees a wide range of educational opportunities for its PhD students. They consist of advanced courses, seminars and topical courses in the Netherlands, and international experience in the form of workshops, summer schools or extended research visits abroad. 149 Appendix A

The Governing Board of the DRSTP decides on admission and monitors the evaluation of progress with a prognosis of ultimate success after the first year. This takes place on the basis of an ‘Education and Supervision Form’ [opleiding- en begeleidingsplan (OBP)] between each individual PhD student and its supervisor(s), to be submitted to and approved by the Board upon admittance. The Educational Board advises the Governing Board. It also assembles the content of the yearly programme of regular activities. Standard advanced courses are published in a nationwide survey. Special PhD courses are offered within the DRSTP, in quantum field theory, statistical physics and in theoretical condensed matter physics, or result from joint efforts with other research schools.

The input of graduate students in the school takes place in the form of a PhD Stu- dent Council that meets regularly with the scientiﬁc director and the chairman of the Governing Board and Educational Board (which also has one student member). Individual members of the DRSTP play a pivotal role in helping to organize many summer schools and workshops, in the Netherlands as well as abroad, and in serving as teachers in all the activities that the DRSTP undertakes by itself or in cooperation with others.

Other responsibilities The responsibilities of the DRSTP include: the promotion of a stimulating research environment in theoretical physics setting uniform standards of quality making educational supplements available tailored to individual research needs.

The Board also develops a wide range of activities in order to support an exciting research climate from fund-raising, e.g. for postdoctoral fellows, guest teachers or international mobility of DRSTP students, to the selection of visiting professors, for example on the Kramers (UU), Lorentz (UL) or Van der Waals (UvA) Chairs. DRSTP Annual Report 2012 150 Appendix B Selection and supervision procedure of PhD students

When a PhD research position opens up with one of the participating partners, there is usually an open round of applications. Important criteria in the selection procedure are the potential of the student for doing independent scientific research and the level and skills demonstrated in the Master’s program. Admission to the DRSTP requires the submission of an ‘Education and Supervision Form’ [opleiding- en begeleidingsplan (OBP)], containing a global description of educational activities with details provided for the first year. The plan also specifies how individual guidance will be provided under responsibility of the thesis advisor. The Research School safeguards a consistent implementation of the agreement, with uniform standards. The plan has to be submitted to the DRSTP Bureau. Formal admission is subject to approval by the Governing Board. After one year the progress is evaluated, based on an interview with the thesis advisor and an independent second referee. The school safeguards this procedure without in- terfering with the responsibilities of the employer. Participation in the educational program is an explicit element of the evaluation: students are expected to attend at least two DRSTP postgraduate schools and the DRSTP symposium ‘Trends in The- ory’. The outcome of the evaluation will reflect on whether the student will be able to complete the research program within the amount of time allotted. If the prognosis is negative, the student will be asked to leave the DRSTP. Such outcomes should be, and are, extremely rare provided proper care is given to the initial selection. A student can appeal a negative evaluation with the Governing Board of the school; a decision will be reached within one month. If a student does leave the school before completing the PhD program, a diploma, specifying the student’s accomplishments in the educational program, will be provided. After the first year, throughout the duration of the PhD project, the progress will be closely monitored, for example by additional yearly evaluation interviews.
