Process interpretation of current entropic bounds
Cesare Nardini, Hugo Touchette
We show for Markov diffusion processes that the quadratic entropic bound, recently derived for the rate functions of nonequilibrium currents, can be seen as being produced by an ef…
Asymptotic equivalence of probability measures and stochastic processes
Hugo Touchette
Let and be two probability measures representing two different probabilistic models of some system (e.g., an -particle equilibrium system, a set of random graphs wit…
Subexponentially growing Hilbert space and nonconcentrating distributions in a constrained spin model
Jason R. Webster, Michael Kastner
Motivated by recent experiments with two-component Bose-Einstein condensates, we study fully-connected spin models subject to an additional constraint. The constraint is responsibl…
Introduction to dynamical large deviations of Markov processes
Hugo Touchette
These notes give a summary of techniques used in large deviation theory to study the fluctuations of time-additive quantities, called dynamical observables, defined in the context…
Universal equilibrium scaling functions at short times after a quench
Markus Karl, Halil Cakir, Jad C. Halimeh +3
By analyzing spin-spin correlation functions at relatively short distances, we show that equilibrium near-critical properties can be extracted at short times after quenches into th…
Classical and quantum filaments in the ground state of trapped dipolar Bose gases
Fabio Cinti, Massimo Boninsegni
We study by quantum Monte Carlo simulations the ground state of a harmonically confined dipolar Bose gas with aligned dipole moments, and with the inclusion of a repulsive two-body…
