Ergodicity and large deviations in physical systems with stochastic dynamics

RL Jack - The European Physical Journal B, 2020 - Springer
In ergodic physical systems, time-averaged quantities converge (for large times) to their
ensemble-averaged values. Large deviation theory describes rare events where these time …

Finite-size scaling of a first-order dynamical phase transition: Adaptive population dynamics and an effective model

T Nemoto, RL Jack, V Lecomte - Physical review letters, 2017 - APS
We analyze large deviations of the time-averaged activity in the one-dimensional
Fredrickson-Andersen model, both numerically and analytically. The model exhibits a …

Finite-time and finite-size scalings in the evaluation of large-deviation functions: Analytical study using a birth-death process

T Nemoto, E Guevara Hidalgo, V Lecomte - Physical Review E, 2017 - APS
The Giardinà-Kurchan-Peliti algorithm is a numerical procedure that uses population

Dynamical phase coexistence in the Fredrickson–Andersen model

RL Jack, T Nemoto, V Lecomte - Journal of Statistical Mechanics …, 2020 - iopscience.iop.org
We analyse a first-order dynamical phase transition that takes place in the Fredrickson–
Andersen (FA) model. We construct a two-dimensional spin system whose thermodynamic …

Nonequilibrium thermodynamic potentials for continuous-time Markov chains

G Verley - Physical Review E, 2016 - APS
We connect the rare fluctuations of an equilibrium (EQ) process and the typical fluctuations
of a nonequilibrium (NE) stationary process. In the framework of large deviation theory, this …

Mapping current and activity fluctuations in exclusion processes: consequences and open questions

M Vanicat, E Bertin, V Lecomte, E Ragoucy - SciPost Physics, 2021 - scipost.org
Considering the large deviations of activity and current in the Asymmetric Simple Exclusion
Process (ASEP), we show that there exists a non-trivial correspondence between the joint …

BEST statistics of Markovian fluxes: a tale of Eulerian tours and Fermionic ghosts

M Polettini - Journal of Physics A: Mathematical and Theoretical, 2015 - iopscience.iop.org
We provide an exact expression for the statistics of the fluxes of Markov jump processes at
all times, improving on asymptotic results from large deviation theory. The main ingredient is …

Dynamical phase transitions for the activity biased Ising model in a magnetic field
