Influence of diffusion on models for non-equilibrium wetting

TL;DR

This paper investigates how adding single-particle diffusion affects the critical properties of a non-equilibrium wetting model, revealing robustness and identifying a special point where detailed balance is partially broken.

Contribution

It demonstrates that the critical behavior remains robust with diffusion and uncovers a unique point in the phase diagram with partial detailed balance breaking.

Findings

Critical properties are robust under diffusion extension.

Identification of a special phase diagram point with partial detailed balance breaking.

Behavior at the critical point and phase transition line analyzed.

Abstract

It is shown that the critical properties of a recently studied model for non-equilibrium wetting are robust if one extends the dynamic rules by single-particle diffusion on terraces of the wetting layer. Examining the behavior at the critical point and along the phase transition line, we identify a special point in the phase diagram where detailed balance of the dynamical processes is partially broken.
