Thermodynamic formalism for systems with Markov dynamics

V Lecomte, C Appert-Rolland, F Van Wijland - Journal of statistical physics, 2007 - Springer
The thermodynamic formalism allows one to access the chaotic properties of equilibrium
and out-of-equilibrium systems, by deriving those from a dynamical partition function. The …

This paper provides an introduction to some stochastic models of lattice gases out of
equilibrium and a discussion of results of various kinds obtained in recent years. Although …

Large deviations of the empirical flow for continuous time Markov chains

L Bertini, A Faggionato, D Gabrielli - Annales de l'IHP Probabilités et …, 2015 - numdam.org
We consider a continuous time Markov chain on a countable state space and prove a joint
large deviation principle for the empirical measure and the empirical flow, which accounts …

Large deviations of the empirical currents for a boundary-driven reaction diffusion model

T Bodineau, M Lagouge - 2012 - projecteuclid.org
We derive a large deviation principle for the empirical currents of lattice gas dynamics which
combine a fast stirring mechanism (Symmetric Simple Exclusion Process) and …

Large deviations conditioned on large deviations II: fluctuating hydrodynamics

B Derrida, T Sadhu - Journal of Statistical Physics, 2019 - Springer
For diffusive many-particle systems such as the SSEP (symmetric simple exclusion process)
or independent particles coupled with reservoirs at the boundaries, we analyze the density …

Variational structures beyond gradient flows: a macroscopic fluctuation-theory perspective

RIA Patterson, DRM Renger, U Sharma - Journal of Statistical Physics, 2024 - Springer
Macroscopic equations arising out of stochastic particle systems in detailed balance (called

Flux large deviations of independent and reacting particle systems, with implications for macroscopic fluctuation theory

DRM Renger - Journal of Statistical Physics, 2018 - Springer
We consider a system of independent particles and a system of reacting particles on a
discrete state space. For the independent case, we rigorously prove a dynamic large …
