Fluctuation, Dissipation and the Arrow of Time

TL;DR

This paper introduces fluctuation relations and explores their implications for understanding how irreversible macroscopic behavior arises from microscopic reversible dynamics, shedding light on the arrow of time.

Contribution

It provides an introduction to fluctuation relations and discusses their connection to dissipation and the arrow of time, offering new insights into irreversibility.

Findings

Fluctuation relations relate microscopic reversibility to macroscopic irreversibility.

They provide a framework for understanding dissipation in nonequilibrium systems.

The paper discusses the impact of fluctuation relations on the arrow of time concept.

Abstract

The recent development of the theory of fluctuation relations has led to new insights into the ever-lasting question of how irreversible behavior emerges from time-reversal symmetric microscopic dynamics. We provide an introduction to fluctuation relations, examine their relation to dissipation and discuss their impact on the arrow of time question.
