  • String Theory Methods for Condensed Matter Physics Horatiu Nastase Frontmatter More Information
    Cambridge University Press 978-1-107-18038-3 — String Theory Methods for Condensed Matter Physics Horatiu Nastase Frontmatter More Information String Theory Methods for Condensed Matter Physics The discovery of a duality between Anti–de Sitter spaces (AdS) and Conformal Field The- ories (CFT) has led to major advances in our understanding of quantum field theory and quantum gravity. String theory methods and AdS/CFT correspondence maps provide new ways to think about difficult condensed matter problems. String theory methods based on the AdS/CFT correspondence allow us to transform problems so they have weak interac- tions and can be solved more easily. They can also help map problems to different descrip- tions, for instance, mapping the description of a fluid using the Navier-Stokes equations to the description of an event horizon of a black hole using Einstein’s equations. This text- book covers the applications of string theory methods and the mathematics of AdS/CFT to areas of condensed matter physics. Bridging the gap between string theory and condensed matter, this is a valuable textbook for students and researchers in both fields. Hora¸tiu Nastase˘ is a Researcher at the Institute for Theoretical Physics at the State University of São Paulo, Brazil. To date, his career has spanned four continents. As an undergraduate he studied at the University of Bucharest and Copenhagen University. He later completed his Ph.D. at the State University of New York, Stony Brook, before moving to the Institute for Advanced Study, Princeton, where his collaboration with David Berenstein and Juan Maldacena defined the pp-wave correspondence.

  • N = 1 Dualities and the Dynamics of Brane Anti-Brane Systems
    N = 1 dualities and the dynamics of brane anti-brane systems David Berenstein School of Natural Sciences Institute for Advanced Study Work w. M. Douglas. hep-th 0207027 1 Introduction One of the most striking results in the modern study of N = 1 supersymmetric gauge theory was Seiberg’s discovery of an IR duality between two QCD-like theories, both with Nf flavors of quarks (fundamental chiral superfields), but with different gauge groups. This discovery connects two quantum theories which at the classical level have no resemblance to each other. The two theories are • SU(Nc) supersymmetric gauge theory with Nf flavours Qi, Q˜i, and no superpotential. • SU(NF − Nc) supersymmetric gauge theory with Nf flavours qi, q˜i, meson fields Mij which are singlets of the gauge group, and superpotential Mijqiq˜j 2 A popular way to study N = 1 supersymmetric gauge theories is to realize them geometrically in string theory, as suspended brane constructions, D- branes wrapping cycles in Calabi-Yau manifolds, orbifolds, and otherwise. • Hanany-Witten • S. Elitzur, A. Giveon and D. Kutasov • B. Feng, A. Hanany and Y. H. He (toric duality ?) • F. Cachazo, B. Fiol, K. A. Intriligator, S. Katz and C. Vafa They do not explain in a satisfying manner the superpotential data that is necessary to make the dualities work. The objective of this talk is to show how to overcome this obstacle so that one can derive the (classical) superpotential of the dual theory from first principles. 3 Outline • Field theories realized by IIb holomorphic branes on CY. • Central charge and gauge couplings.

  • Marginal and Relevant Deformations of N= 4 Field Theories and Non
    Preprint typeset in JHEP style. - HYPER VERSION ILL-(TH)-00-04 Marginal and Relevant Deformations of N=4 Field Theories and Non-Commutative Moduli Spaces of Vacua David Berenstein,∗Vishnu Jejjala,†and Robert G. Leigh‡ Department of Physics University of Illinois at Urbana-Champaign Urbana, IL 61801 Abstract: We study marginal and relevant supersymmetric deformations of the N = 4 super-Yang-Mills theory in four dimensions. Our primary innovation is the interpretation of the moduli spaces of vacua of these theories as non-commutative spaces. The construction of these spaces relies on the representation theory of the related quantum algebras, which are obtained from F -term constraints. These field theories are dual to superstring theories propagating on deformations of the AdS S5 5× geometry. We study D-branes propagating in these vacua and introduce the ap- propriate notion of algebraic geometry for non-commutative spaces. The resulting moduli spaces of D-branes have several novel features. In particular, they may be interpreted as symmetric products of non-commutative spaces. We show how mir- ror symmetry between these deformed geometries and orbifold theories follows from arXiv:hep-th/0005087v1 9 May 2000 T-duality. Many features of the dual closed string theory may be identified within the non-commutative algebra. In particular, we make progress towards understand- ing the K-theory necessary for backgrounds where the Neveu-Schwarz antisymmetric tensor of the string is turned on, and we shed light on some aspects of discrete anomalies based on the non-commutative geometry. Keywords: D-branes, AdS/CFT, non-commutative geometry, K-theory.

In particular, we work out the topological conditions on the embedding of the singularity inside a compact CY threefold, that select hypercharge as the only light U(1) gauge factor. We apply this insight to the proposed open string realization of the SM of hep-th/0508089, based on a D3-brane at a dP8 singularity, and present a geometric construction of a compact Calabi-Yau threefold with all the required topological properties.

  • Matrix Description of M-Theory on T 6
    HU-EP-97/44 hep-th/9707259 July 31, 1997 Matrix Description of M-theory on T 6 Ilka Brunner and Andreas Karch Humboldt-Universit¨at zu Berlin Institut f¨ur Physik Invalidenstraße 110 D-10115 Berlin, Germany Email: [email protected] [email protected] Abstract We give some evidence that the worldvolume theory of the M-theory KK 6-brane is governed by a non-critical membrane theory. We use this theory to give a matrix description of M- theory on T 6. 1. Introduction Recently there has been much excitement about a new approach to capture the non-perturbative aspects of supersting theory: matrix theory ([17]). “Matrix theory is a nonperturbative Hamiltonian formalism for the theory formerly known as string theory/M theory” ([31]). Nevertheless this nice new theory has a serious flaw: it is formulated in the infinite mo- mentum frame (IMF), sometimes called lightcone gauge. Thus in addition to not being manifestly covariant the theory becomes background dependent. That means for every new background (e.g. for various compactifications) one needs a different Hamiltonian, ergo a new theory. Since we are mostly interested in compactifications down to four dimensions (after all, this is the real world) it is a very interesting problem to find the matrix description of M-theory compactifications. Since matrix theory is non-local, the compactified theory has ’more’ degrees of freedom than the theory describing flat space. Very early it has been realised that compactifications of M-theory on tori can be realised by substituting the original 0+1 dimensional quantum mechanics by d+1 dimensional SYM with 16 supercharges ([17,20]).

E-mail: [email protected], [email protected] 1 Abstract: We study classical solutions to the Nambu-Goto string on AdS2 × S and 1 AdS3 × S corresponding to strings stretched between wrapped branes extending in AdS. The solutions are obtained by analytic continuation of giant magnon solutions, cut at the position of the branes. These solutions carry one or two SO(2; 4) charges and a single 1 SO(6) charge. We compute their energies and show their relation to 2 -BPS geometries. Their relevance to the SL(2) sector of N = 4 SYM is also discussed.

  • Open Spin Chains for Giant Gravitons and Relativity
    Open spin chains for giant gravitons and relativity David Berenstein, Eric Dzienkowski Department of Physics, University of California at Santa Barbara, CA 93106 We study open spin chains for strings stretched between giant graviton states in the = 4 SYM field theory in the collective coordinate approach. We study the N boundary conditions and the effective Hamiltonian of the corresponding spin chain to two loop order. The ground states of the spin chain have energies that match the relativistic dispersion relation characteristic of massive W boson particles on the worldvolume of the giant graviton configurations, up to second order in the limit where the momentum is much larger than the mass. We find evidence for a non- renormalization theorem for the ground state wave function of this spin chain system. We also conjecture a generalization of this result to all loop orders which makes it compatible with a fully relativistic dispersion relation. We show that the conjecture follows if one assumes that the spin chain admits a central charge extension that is sourced by the giant gravitons, generalizing the giant magnon dispersion relation for closed string excitations. This provides evidence for ten dimensional local physics mixing AdS directions and the five-sphere emerging from an = 4 SYM computa- N tion in the presence of a non-trivial background (made of D-branes) that break the conformal field theory of the system. arXiv:1305.2394v2 [hep-th] 4 Jun 2013 2 I. INTRODUCTION The AdS/CFT correspondence [1] suggests that there should be a relation between the low energy effective field theories of string theory (both with open and closed strings) or M-theory on AdS spaces and the dual gauge theory.

  • On the Moduli Spaces of M (Atrix)-Theory Compactifications
    UTTG–08–97 hep-th/9704087 April 10, 1997 On the Moduli Spaces of M(atrix)-Theory Compactifications David Berenstein, Richard Corrado, and Jacques Distler ∗ Theory Group, Department of Physics University of Texas at Austin Austin TX 78712 USA Email: [email protected] Email: [email protected] Email: [email protected] Abstract By identifying the moduli space of coupling constants in the SYM description of toroidal arXiv:hep-th/9704087v1 10 Apr 1997 compactifications of M(atrix)-Theory, we construct the M(atrix) description of the moduli spaces of Type IIA string theory compactified on T n. Addition of theta terms to the M(atrix) SYM produces the shift symmetries necessary to recover the correct global structure of the moduli spaces. Up to n = 3, the corresponding BPS charges transform under the proper representations of the U-duality groups. For n = 4, 5, if we make the ans¨atz of including the BPS charges corresponding to the wrapped M-theory 5-brane, the correspondence with Type IIA continues to hold. However, for n = 6, we find additional charges for which there are no obvious candidates in M(atrix)-Theory. ∗Research supported in part by the Robert A. Welch Foundation and NSF Grant PHY 9511632. 1. Introduction One of the principles which drove the recent “revolution” in string theory was Witten’s dis- covery of M-Theory as a limit of Type IIA strings. Building on results of Townsend [1] and others, he realized that the spectrum of BPS-saturated threshold bound states of RR charges in Type IIA string theory were in direct correspondence with the Kaluza-Klein spectrum of the D = 11 supergravity multiplet with the 11th dimension compactified on a circle of radius r = λ2/3, where λ is the IIA string coupling [2].
