What is nonequilibrium?
Christian Maes
TL;DR
This paper provides an overview of nonequilibrium statistical mechanics, contrasting it with equilibrium, and discusses historical developments and modern concepts like entropy fluxes and dynamical activity.
Contribution
It offers a comprehensive lecture-style summary of key principles, historical perspectives, and recent advances in the understanding of nonequilibrium systems.
Findings
Characterization of nonequilibrium conditions
Historical insights from Boltzmann and Onsager
Introduction of modern concepts like local detailed balance and dynamical fluctuation theory
Abstract
Lecture notes on elements of nonequilibrium statistical mechanics: (1) a characterization of the nonequilibrium condition, largely by contrast to equilibrium; (2) a retelling of some of the great performances of the more distant past, including the perspectives of Boltzmann and Onsager; and (3) more recent methods and concepts, from local detailed balance and the identification of entropy fluxes to dynamical fluctuation theory, and the importance of dynamical activity.
