System Size Stochastic Resonance from the Viewpoint of the Nonequilibrium Potential

TL;DR

This paper investigates system size stochastic resonance in extended systems using nonequilibrium potential analysis, providing a physical interpretation and examining boundary condition effects.

Contribution

It introduces a novel approach to understanding stochastic resonance via nonequilibrium potential symmetry in spatially extended systems.

Findings

Nonequilibrium potential symmetry explains stochastic resonance.

Boundary conditions significantly influence resonance behavior.

The approach applies broadly to similar extended systems.

Abstract

We analyze the phenomenon of system size stochastic resonance in a simple spatially extended system by exploiting the knowledge of the nonequilibrium potential. We show that through the analysis of that potential, and particularly its "symmetry", we can obtain a clear physical interpretation of this phenomenon in a wide class of extended systems, and also analyze, for the same simple model, the effect of a general class of boundary conditions (albedo) on this kind of phenomena.
