Statistical Mechanics Seminar, R, Car, "Entangled protons in ice"

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"

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...

Statistical Mechanics Seminar, G. Gallavotti, "Time Evolution and Stationary States of Classical and Quantum"

Statistical Mechanics Seminar, G. Gallavotti, "Time Evolution and Stationary States of Classical and Quantum"
Wed, Oct 12, 2011, 2:00 pm to 3:30 pm
ABSTRACT: A chaotic system under periodic forcing can develop a periodically visited strange attractor. We discuss simple models in which the phenomenon, quite easy to see in numerical simulations, can be completely studied analytically.

Math Phys Seminar: Simone Warzel (Tech. Univ. Munich) "Absence of mobility edge for the Anderson random potential on tree graphs at weak disorder"

Math Phys Seminar: Simone Warzel (Tech. Univ. Munich) "Absence of mobility edge for the Anderson random potential on tree graphs at weak disorder"
Tue, Oct 11, 2011, 4:30 pm to 6:00 pm
We discuss recently established criteria for the formation of extended states on tree graphs in the presence of disorder. These criteria have the surprising implication that for bounded random potentials, as in the Anderson model, in the weak disorder regime there is no transition to a spectral regime of Anderson localization in the form usually...

High Energy Theory Seminar - Callum Quigley - University of Chicago - Constraints on String Cosmology

High Energy Theory Seminar - Callum Quigley - University of Chicago - Constraints on String Cosmology
Tue, Oct 11, 2011, 1:00 pm to 2:30 pm
Abstract: String theory contains sources like orientifold planes that support higher derivative interactions. These interactions make possible static flux compactifications which are forbidden in supergravity. They can also lead to violations of the strong energy condition (SEC) which is needed for an accelerating universe.

High Energy Physics Seminar- Hiro Tanaka-"Recent results from the Tokai-to-Kamioka (T2K) Experiment"

High Energy Physics Seminar- Hiro Tanaka-"Recent results from the Tokai-to-Kamioka (T2K) Experiment"
Mon, Oct 10, 2011, 2:00 pm to 3:00 pm
I will report on recent results from the Tokai-to-Kamioka (T2K) experiment, which aims to make high sensitivity and precise studies of neutrino oscillation using an intense off-axis muon neutrino beam produced by the Japan Proton Accelerator Complex (J-PARC) and directed towards the Super Kamiokande (SK) detector 295 km away.

High Energy Theory Seminar - Jared Kaplan, SLAC, Stanford University - "A Natural Language for AdS/CFT Correlators and the Holographic S-Matrix".

High Energy Theory Seminar - Jared Kaplan, SLAC, Stanford University - "A Natural Language for AdS/CFT Correlators and the Holographic S-Matrix".
Fri, Oct 7, 2011, 1:30 pm to 3:00 pm
"We provide dramatic evidence that `Mellin space' is the natural home for correlation functions in CFTs with weakly coupled bulk duals. In Mellin space, CFT correlators have poles corresponding to an OPE decomposition into `left' and `right' sub-correlators, in direct analogy with the factorization channels of scattering amplitudes.

J.L. Lebowitz, Time Evolution and Stationary States of Classical and Quantum

J.L. Lebowitz, Time Evolution and Stationary States of Classical and Quantum
Wed, Oct 5, 2011, 2:00 pm to 3:30 pm
Abstract: I will review both old and recent work about the time dependence and steady states of isolated macroscopic systems as well as those in contact with infinite thermal reservoirs. The emphasis will be on quantum systems and will include a discussion of the micro/macro connection in isolated ones and the derivation of a master equation...

High Energy Theory Seminar - Bartek Czech, The University of British Columbia - "Three Perspectives on Eternal Inflation"

High Energy Theory Seminar - Bartek Czech, The University of British Columbia - "Three Perspectives on Eternal Inflation"
Tue, Oct 4, 2011, 1:00 pm to 2:30 pm
PLEASE NOTE CHANGE IN TIME AND ROOM I will discuss three ways in which (the string landscape and) eternal inflation is fun: (1) because it motivates revisiting some beautiful, classic calculations; (2) because its global description requires asking novel questions with possible broad ramifications; and (3) because it leads to experimental...

Fri, Sep 30, 2011, 1:30 pm to 6:00 pm
Abstract: Time-reversal invariant band insulators can be separated into two categories: `ordinary' insulators and `topological' insulators. Topological band insulators have low-energy edge modes that cannot be gapped without violating time-reversal symmetry, while ordinary insulators do not.
