### High Energy Physcis Seminar- Sue Ann Koay-"Excavating for SUSY: A dark matter search at the Large Hadron Collider experiment"

Mon, Dec 19, 2011, 2:45 pm to 4:15 pm

One of the challenges of 21st century particle physics is a deficit of observations to constrain/shape hypotheses for what may be "the"Theory Of Everything, or at least a next stage in our development of such.

### Physics Holiday Party

Fri, Dec 16, 2011, 3:00 pm to 6:00 pm

Please join us today at 3pm for some Holiday fun including caroling by graduate students!

### High Energy Theory Seminar - Jumpstarting the all-loop S-matrix of N=4 super Yang-Mills - Simon Caron-Huot, IAS

Fri, Dec 16, 2011, 1:30 pm to 3:00 pm

I will discuss recent progress in understanding loop-level scattering amplitudes in planar N=4 SYM.Compared with previous efforts aimed at exploiting integrability of this gauge theory,our approach differs mainly in its focus on canonical infrared-safe quantities, and its use of so-called momentum twistor variables.I will discuss how the first...

### Gravity Group Astrophysics|Cosmology Lunch: Immanuel Buder (KICP, University of Chicago), "CMB Polarization Results from the QUIET Experiment"

Fri, Dec 16, 2011, 12:00 pm to 1:30 pm

Abstract: Inflationary cosmology postulates that the Universe underwent a period of accelerated expansion in the first $10^{-30}$,s after the Big Bang. Inflationary models are attractive because they solve outstanding problems in cosmology: the origin of structure, the absence of monopoles, and the horizon and flatness problems.

Abstract: A crossing probability is the probability of finding a critical cluster that touches specified boundary arcs.

### High Energy Theory Informal Seminar - Multiplicities from black-hole formation in heavy-ion collisions - Anastasios Taliotis - University of Crete

Tue, Dec 13, 2011, 12:30 pm to 2:30 pm

Abstract: The formation of trapped surfaces in the head-on collision of shock waves in conformal and non-conformal backgrounds is investigated. The backgrounds include all interesting confining and non-confining backgrounds that may be relevant for QCD. Several transverse profiles of the shocks are investigated including distributions that fall-...

### High Energy Theory Seminar - Ben Freivogel, Lawrence Berkeley National Laboratory

Mon, Dec 12, 2011, 2:30 pm to 4:00 pm

### Condensed Matter Seminar, Emanuele Dalla Torre, "Non-equilibrium quantum critical states: a real-time RG approach"

Mon, Dec 12, 2011, 1:15 pm to 2:30 pm

Abstract: Equilibrium thermal noise is known to destroy the scale invariance of quantum critical points, through the introduction of a finite thermal length. What are the effects of non-equilibrium time-dependent noise?

### Statistical Mechanics Seminar, V. Mastropietro, "Universal conductivity in graphene; some rigorous results and open problems"

Wed, Dec 7, 2011, 2:00 pm to 3:30 pm

Abstract: Recent experiments have found an universal value for the dynamic conductivity in graphene, fully confirming theoretical predictions based on a non interacting tight binding model. This however poses a problem since one could expect a many body renormalization of the non interacting value of the conductivity due to the interaction.

### HET Seminar - ABJM theory as a Fermi gas - Pavel Putrov - University of Geneva

Mon, Dec 5, 2011, 2:30 pm to 4:00 pm

Abstract: The partition function on the three-sphere of many supersymmetric Chern-Simons-matter theories reduces, by localization, to a matrix model. In this talk I will describe a new method to study these models in the M-theory limit, but at all orders in the 1/N expansion. The method is based on reformulating the matrix model as the partition...

### Biophysics Seminar Series - Olga Dudko, UCSD

### John Estes - University of Leuven, Belgium - Locally localized gravity in string theory

Fri, Dec 2, 2011, 1:30 pm to 3:00 pm

Abstract: Localized gravity is the idea of obtaining an effective 4D gravitational theory from higher-dimensions without compactification. This is done by localizing a set of gravitational degrees of freedom along a 4D submanifold (brane-world), while the coupling of the brane-world to the remaining gravitational degrees of freedom is suppressed.

### CANCELED Statistical Mechanics Seminar, J Yngvason, "Interacting Bosons in Random Potentials Interacting Bosons in"

Wed, Nov 30, 2011, 2:00 pm to 3:30 pm

Abstract: : In contrast to the cases of single particle Schrödinger
operators and ideal Bose gases the effects of random external
potentials on many-body systems of interacting particles is still poorly
understood. In the lecture the effects of random scatterers on the ground
state of the one-dimensional Lieb-Liniger model of interacting bosons,
