A Note on Non-equilibrium Work Fluctuations and Equilibrium Free Energies
Classical Statistical Mechanics Thermodynamics Non-equilibrium and Irreversible Thermodynamics
font style='font-size:12px;'>
2010/11/24
We consider in this paper, a few important issues in non-equilibrium work fluctuations and
their relations to equilibrium free energies. First we show that Jarzynski identity can be viewed as a cumul...

Diagnosing Deconfinement Topological Order
font style='font-size:12px;'>
2011/6/2
Topological or deconfined phases are characterized by emergent, weakly fluctuating, gauge fields. In condensed matter settings they inevitably come coupled to excitations that carry the corresponding ...
Attempt-time Monte Carlo: an alternative for simulation of stochastic jump processes with time-dependent transition rates
Attempt-time Monte Carlo simulation of stochastic jump processes time-dependent transition rates
font style='font-size:12px;'>
2010/11/24
cWe present a new method for simulating Markovian jump processes with time-dependent tran-
sitions rates, which avoids the transformation of random numbers by inverting time integrals over the rates....
Transition probabilities and dynamic structure factor in the ASEP conditioned on strong flux
Transition probabilities dynamic structure factor strong flux

2010/11/23
We consider the asymmetric simple exclusion processes (ASEP) on a ring constrained to produce an atypically large flux, or an extreme activity. Using quantum free fermion techniques we find the time-d...

In this paper the problem of comparing initial data to a reference solution for the vacuum
Einstein field equations is considered. This is not done in a coordinate sense, but through
quantification ...

Non-Abelian Vortex Graphenelike Systems
font style='font-size:12px;'>
2010/11/22
The Abelian Higgs model is an appropriate field theoretic framework for the description of super-conductivity and its topological excitations(Nielson-Olesen-Abrikosov vortex). Recently, C.-Y. Hou etl ...
Holographic description of large N gauge theory
Holographic description large N gauge theory
font style='font-size:12px;'>
2011/1/14
Based on the earlier work [S.-S. Lee, Nucl. Rev. B 832, 567 (2010)], we derive a holographic dual for the D-dimensional U(N) lattice gauge theory from a first principle construction. The resulting the...
On the Unruh effect in de Sitter space
Unruh effect de Sitter space
font style='font-size:12px;'>
2010/12/20
We give an interpretation of the temperature in de Sitter universe in terms of a dynamical Unruh effect associated with the Hubble sphere. As with the quantum noise perceived by a uniformly accelerate...
What makes slow samples slow in the Sherrington-Kirkpatrick model
slow samples Sherrington-Kirkpatrick model
font style='font-size:12px;'>
2010/11/23
Using results of a Monte Carlo simulation of the Sherrington-Kirkpatrick model, we try to charac-terize the slow disorder samples, namely we analyze visually the correlation between the relaxation tim...

2010/11/19
Predicting nonequilibrium fluctuations requires a knowledge of nonequilibrium distribution functions.Despite the distributions’ fractal character some theoretical results, “Fluctuation Theorems”,remin...
A simple protocol for the probability weights of the simulated tempering algorithm: applications to first-order phase transitions
simulated tempering first-order phase transitions eigenvalues of the transfer matrix Ising and lattice-gas models
font style='font-size:12px;'>
2010/11/19
The simulated tempering (ST) is an important method to deal with systems whose phase spaces are hard to sample ergodically. However, it uses accepting probabilities weights which often demand involvin...

We consider spin-polarized abelian quantum Hall states in the Tao-Thouless limit, ie on a thin
torus. For any filling factor = p/q a well-defined sector of low-energy states is dentified and the ex...
