Asymmetry of the work probability distribution

TL;DR

This paper demonstrates that in nonlinear systems transitioning between equilibrium states under external forces, the work probability distribution is generally asymmetric, supported by analytical and numerical evidence.

Contribution

It reveals the inherent asymmetry in work distributions for nonlinear systems during state transitions, combining analytical and numerical approaches.

Findings

Work distribution is asymmetric in nonlinear systems.

Analytical and numerical methods confirm the asymmetry.

Transition dynamics influence work distribution shape.

Abstract

We show, both analytically and numerically, that for a nonlinear system making a transition from one equilibrium state to another under the action of an external time dependent force, the work probability distribution is in general asymmetric.
