Depinning and wetting in nonequilibrium systems

TL;DR

This paper extends the concept of wetting from equilibrium to nonequilibrium systems with anisotropic interactions, identifying phase coexistence and characterizing wetting transitions.

Contribution

It introduces a framework for nonequilibrium wetting, analyzing critical and complete transitions, and explores phase coexistence in parameter space.

Findings

Identified regions of phase coexistence between wet and non-wet phases.

Characterized both critical and complete wetting transitions.

Compared equilibrium and nonequilibrium wetting behaviors.

Abstract

We present an extension of equilibrium wetting to nonequilibrium situations particularly suited to systems with anisotropic interactions. Both critical and complete wetting transitions were found and characterized. We have identified a region in the space of parameters (temperature and chemical potential) where the wet and non-wet phases coexist. Emphasis is made on the analogies and differences between equilibrium and nonequilibrium wetting.
