Microcanonical analysis of the Curie-Weiss anisotropic quantum Heisenberg model in a magnetic field
Gerrit Olivier, Michael Kastner
The anisotropic quantum Heisenberg model with Curie-Weiss-type interactions is studied analytically in several variants of the microcanonical ensemble. (Non)equivalence of microcan…
Large deviations for correlated random variables described by a matrix product ansatz
Florian Angeletti, Hugo Touchette, Eric Bertin +1
We study the large deviations of sums of correlated random variables described by a matrix product ansatz, which generalizes the product structure of independent random variables t…
Weak-noise limit of a piecewise-smooth stochastic differential equation
Yaming Chen, Adrian Baule, Hugo Touchette +1
We investigate the validity and accuracy of weak-noise (saddle-point or instanton) approximations for piecewise-smooth stochastic differential equations (SDEs), taking as an illust…
Nonequilibrium microcanonical and canonical ensembles and their equivalence
Raphael Chetrite, Hugo Touchette
Generalizations of the microcanonical and canonical ensembles for paths of Markov processes have been proposed recently to describe the statistical properties of nonequilibrium sys…
Universal threshold for the dynamical behavior of lattice systems with long-range interactions
Romain Bachelard, Michael Kastner
Dynamical properties of lattice systems with long-range pair interactions, decaying like 1/r^α with the distance r, are investigated, in particular the time scales governing the re…
Energy Landscape of the Finite-Size Mean-field 3-Spin Spherical Model
Dhagash Mehta, Daniel A. Stariolo, Michael Kastner
We study the 3-spin spherical model with mean-field interactions and Gaussian random couplings. For moderate system sizes of up to 20 spins, we obtain all stationary points of the…
Fluctuation relations without uniform large deviations
Giacomo Gradenigo, Alessandro Sarracino, Andrea Puglisi +1
We study the fluctuations of a stochastic Maxwell-Lorentz particle model driven by an external field to determine the extent to which fluctuation relations are related to large dev…
