(Image credit: HSC Collaboration / Kavli IPMU.) Kavli IPMU Annual Report 2013 1 Foreword It is a good time to reflect on the first seven years of our institute. The Kavli Institute for the Phys- ics and Mathematics of the Universe (Kavli IPMU) was founded seven years ago on October 1, 2007. We proposed to address five basic questions about the Universe, how it began, what it is made of, what its fate is, what its fundamental laws are, and why we exist in it. We do so by com- bining mathematics, physics, and astronomy, employing accelerator-based experiments, under- ground experiments, and observations at telescopes. This Institute literally started from scratch, but now has grown to a size of about 150 people on site including graduate students and support staff. Overall, I believe the Institute came out to be exactly as proposed. Our unique building allows mathematicians, physicists and astronomers to be under the same roof, sharing seminars and the daily teatime. Interdisciplinary discussions have become a commonplace. The Institute is highly international; more than a half of the members are not Japanese nationals. Every member was hired anew, and the quality of the hires is clear; about 90% of the postdocs have been offered po- sitions at other excellent institutions after their term at Kavli IPMU, and more than a third of them are on faculty positions by now. Our citation counts are similar to other world-leading research institutions. Thanks to several high profile papers and high international visibility, our members are invited to major conferences as keynote or summary speakers. We advertise positions interna- tionally and attract nearly a thousand applications each year. Many papers were written based on mutual inspiration of mathematicians and physicists. Key “in- terpreters” to overcome the language barrier between mathematicians and physicists played critical roles to make it possible. This is crucial to address the question “what are the fundamental laws?” The large projects proposed in the original proposal are producing fruits. The direct dark matter detection experiment XMASS was built and produced world best limits on some candidates. It is addressing the question “what is the Universe made of.” The KamLAND-Zen effort produced the world best limit on neutrinoless double beta decay (this result was published in February, 2013, namely, in FY2012). Hyper Suprime-Cam (HSC) was designed, built, commissioned, and the 300-night survey was approved on the Subaru telescope, one of the largest in the world. Data from the initial few nights are being analyzed. Combined with the theoretical research by our members, they address the question “why do we exist.” Hitoshi Murayama Director We proposed Prime Focus Spectrograph (PFS) in 2009, which is now under construction. The combination of imaging survey using HSC and spectroscopic survey using PFS on the same tele- scope promises to be a world-leading observational program, looking into “the fate of the Uni- verse” a trillion years from now. We are now proposing LiteBIRD satellite experiment to look for

CERN Courier dates back to August 1959, when the first issue appeared, consisting of eight black-and-white pages. Since then it has seen many changes in design and layout, leading to the current full-colour editions of more than 50 pages on average. It went on the web for the High luminosity: first time in October 1998, when IOP Publishing took over the production work. Now, we have taken another step forward with this digital edition, which provides yet another means to access the content beyond the web the heat is on and print editions, which continue as before. Back in 1959, the first issue reported on progress towards the start of CERN’s first proton synchrotron. This current issue includes a report from the physics frontier as seen by the ATLAS experiment at the laboratory’s current flagship, the LHC, as well as a look at work that is under way to get the most from this remarkable machine in future. Particle physics has changed a great deal since 1959 and this is reflected in the article on the emergence of QCD, the theory of the strong interaction, in the early 1970s.

Wallc aCenter for Theoretical Physics and Department of Physics, University of California, Berkeley, CA 94720, U.S.A. bLawrence Berkeley National Laboratory, Berkeley, CA 94720, U.S.A. cInstitute for Advanced Study, Princeton, NJ 08540, USA Abstract: We propose a universal inequality that unifies the Bousso bound with the classical focussing theorem. Given a surface σ that need not lie on a horizon, we define a finite generalized entropy Sgen as the area of σ in Planck units, plus the von Neumann entropy of its exterior. Given a null congruence N orthogonal to σ, the rate of change of Sgen per unit area defines a quantum expansion. We conjecture that the quantum expansion cannot increase along N. This extends the notion of universal focussing to cases where quantum matter may violate the null energy condition. Integrating the conjecture yields a precise version of the Strominger-Thompson Quantum Bousso Bound. Applied to locally parallel light-rays, the conjecture implies a Quantum Null Energy Condition: a lower bound on the stress tensor in terms of the second derivative of the von Neumann entropy. We sketch a proof of this novel relation in quantum field theory. arXiv:1506.02669v1 [hep-th] 8 Jun 2015 Contents 1 Introduction2 2 Classical Focussing and Bousso Bound5 2.1 Classical Expansion5 2.2 Classical Focussing Theorem6 2.3 Bousso Bound7 3 Quantum Expansion and Focussing Conjecture8 3.1 Generalized Entropy

  • A Note on Background (In)Dependence

    A Note on Background (In)Dependence

    RU-91-53 A Note on Background (In)dependence Nathan Seiberg and Stephen Shenker Department of Physics and Astronomy Rutgers University, Piscataway, NJ 08855-0849, USA [email protected], [email protected] In general quantum systems there are two kinds of spacetime modes, those that fluctuate and those that do not. Fluctuating modes have normalizable wavefunctions. In the context of 2D gravity and “non-critical” string theory these are called macroscopic states. The theory is independent of the initial Euclidean background values of these modes. Non- fluctuating modes have non-normalizable wavefunctions and correspond to microscopic states. The theory depends on the background value of these non-fluctuating modes, at least to all orders in perturbation theory. They are superselection parameters and should not be minimized over. Such superselection parameters are well known in field theory. Examples in string theory include the couplings tk (including the cosmological constant) arXiv:hep-th/9201017v2 27 Jan 1992 in the matrix models and the mass of the two-dimensional Euclidean black hole. We use our analysis to argue for the finiteness of the string perturbation expansion around these backgrounds. 1/92 Introduction and General Discussion Many of the important questions in string theory circle around the issue of background independence. String theory, as a theory of quantum gravity, should dynamically pick its own spacetime background. We would expect that this choice would be independent of the classical solution around which the theory is initially defined. We may hope that the theory finds a unique ground state which describes our world. We can try to draw lessons that bear on these questions from the exactly solvable matrix models of low dimensional string theory [1][2][3].

    Standard Model Festival

    Standard Model festival The Hamburg Lepîon-Photon Symposium also marked the tenth anniversary of the discovery at Fermilab of the upsilon particle (beauty quark and antiquark bound together). At a Fermilab celebration of the discovery earlier this year were (left to right) Alvin Tollestrup, Sandy Anderson (with balloon), Hwa Yoh, Leon Lederman, Janine Tollestrup, Drummond Rennie, Martyl Langsdorf and Vivian Bull. The 'Standard Model' of modern particle physics, with the quantum chromodynamics (QCD) theory of inter-quark forces superimposed on the unified electroweak picture, is still unchallenged, but it is not the end of physics. This was the message at the big International Symposium on Lepton and Photon Interactions at High Energies, held in Hamburg from 27-31 July. The conference is a celebration of the Standard Model', admitted Graham Ross of Oxford, given the task of looking beyond. He pointed out a few interesting clouds on the horizon, and echoed the in­ creasing belief that experiments at higher collision energies (1000 GeV for constituent quarks inside nucléons or for electrons) would probe deep inside the Standard Model and reveal some­ thing new. Carlo Rubbia of CERN flew in at the end of the meeting with some suggestions for future machines to explore these far horizons.
