HET Seminar - Andrew Zayakin, LMU, Garching - Exact one-loop strong coupling results for string spectrum in AdS4 x CP3 versus all-loop Bethe Ansatz

HET Seminar - Andrew Zayakin, LMU, Garching - Exact one-loop strong coupling results for string spectrum in AdS4 x CP3 versus all-loop Bethe Ansatz
Mon, Nov 7, 2011, 2:30 pm to 4:00 pm
A non-trivial test of the string vs. integrability correspondence is suggested: exact equivalence is established between strings in AdS4 x CP3 and the Gromov-Vieira all-loop integrable chain. To do that, the complete one- and two-magnon sector of each respective theory are calculated.

Math Phys Seminar: Tatyana Shcherbina (Inst. for Low Temp. Phys., Kharkov, Ukraine) "Characteristic polynomials of the hermitian Wigner and sample co
Tue, Nov 1, 2011, 4:30 pm to 6:00 pm
We consider asymptotics of the correlation functions of characteristic polynomials of the hermitian Wigner matrices $H_n=n^{-1/2}W_n$ and the hermitian sample covariance matrices $X_n=n^{-1}A_{m,n}^*A_{m,n}$. We use the integration over the Grassmann variables to obtain a convenient integral representation.

Massimo Taronna - Scuola Normale Superiore - Higher-Spin Interactions: three-point functions and beyond
Tue, Nov 1, 2011, 1:00 pm to 2:30 pm
Taking String Theory as a ``theoretical laboratory'', I will present handy expressions for bosonic and fermionic (SUSY) higher-spin Noether currents. I will also describe a class of non-local higher-spin Lagrangian couplings that are generically required by the Noether procedure starting from four-points.

Condensed Matter Seminar, Tk Lee, "Recent progress on the variational approach to understand high temperature superconductors".
Mon, Oct 31, 2011, 1:15 pm to 2:30 pm
Abstract: Since the pioneering proposal by Anderson that the superconducting state of high-Tc cuprates can be described by the resonanting-valence-bond (RVB) state, a number of important results to support the idea were obtained by using the variational approach to study the t-J model. However, two major issues were not addressed at the...

Statistical Mechanics Seminar, D. Brydges, "The renormalisation group and recent applications"
Wed, Oct 26, 2011, 2:00 pm to 3:30 pm
Abstract: I will review a method to control irrelevant terms in the renormalisation group and describe an application to self-repelling walk in four dimensions.

Math Phys Seminar: Marija Vucelja (Courant Inst. NYU) "Fractal iso-contours of passive scalar in smooth random flows"

Math Phys Seminar: Marija Vucelja (Courant Inst. NYU) "Fractal iso-contours of passive scalar in smooth random flows"
Tue, Oct 25, 2011, 4:30 pm to 6:00 pm
We consider a passive scalar field under the action of pumping, diffusion and advection by a smooth flow with a Lagrangian chaos. We present theoretical arguments showing that scalar statistics is not conformal invariant and formulate new effective semi-analytic algorithm to model the scalar turbulence.

High Energy Theory Seminar - Lance Dixon, SLAC, Stanford University - "Bootstrapping the three-loop hexagon"

High Energy Theory Seminar - Lance Dixon, SLAC, Stanford University - "Bootstrapping the three-loop hexagon"
Mon, Oct 24, 2011, 2:30 pm to 3:00 pm
Abstract: I discuss how to combine the physical constraints, in particular the operator product expansion for Wilson loops, with the technical power of the "symbol" of pure transcendental functions.

High Energy Theory Seminar - Idse Heemskerk, University of California, Santa Barbara - Prying the CFT from the AdS boundary

High Energy Theory Seminar - Idse Heemskerk, University of California, Santa Barbara - Prying the CFT from the AdS boundary
Fri, Oct 21, 2011, 1:30 pm to 3:00 pm
The holographic principle is puzzling: how can it be that degrees of freedom on the boundary of a spacetime region give rise to approximately local physics in the interior? I will review some aspects of the emergence of local AdS physics from the boundary field theory and then discuss a construction of boundary operators that measure local bulk...

“Entanglement and Quantum Algorithms with Superconducting Circuits

Statistical Mechanics Seminar, R, Car, "Entangled protons in ice"
Wed, Oct 19, 2011, 2:00 pm to 3:30 pm
Abstract: Quantum fluctuations can drive phase transitions in ice. This happens when the protons tunnel between the two equivalent sites on a hydrogen bond. The corresponding dynamics is collective and dominated by strong local correlations originating from the ice rules.

Math Phys Seminar: Sourav Chatterjee (Courant Inst. NYU) "The universal relation between exponents in first-passage percolation"

Math Phys Seminar: Sourav Chatterjee (Courant Inst. NYU) "The universal relation between exponents in first-passage percolation"
Tue, Oct 18, 2011, 4:30 pm to 6:00 pm
It has been conjectured in numerous physics papers that in ordinary first-passage percolation on integer lattices, the fluctuation exponent \chi and the wandering exponent \xi are related through the universal relation \chi=2\xi -1, irrespective of the dimension. This is sometimes called the KPZ relation between the two exponents.

" Quest for new frontier at the LHC" Abstract: The 7 TeV center of mass energy proton-proton machine built in the LEP tunnel is housing 4 major experiments ATLAS, ALICE, CMS and LHCb in its 100 meter underground cavern. These experiments will be recording the particles left by the debris from the collisions and looking for new physics...

High Energy Physcis Seminar- Dmytro Kovalskyi-SLAC-"Search for the Higgs Boson with CMS Detector"
Tue, Oct 18, 2011, 2:00 pm to 3:00 pm
2011 has been the year when the Large Hadron Collider (LHC) became the world's leading experimental facility in the area of the fundamental particle interactions. The amount of data available for analysis is increasing exponentially. The search for the Higgs boson is entering its final phase and it is very likely that we will know for sure if it...
