Stochastic resonance in a realistic model for surface adsorption

We study a model for a monolayer single adsorbate system used to describe pattern formation on adsorbates with lateral interactions, when it is submitted to pressure oscillations. Through numerical and analytical (based on a two-state approximation) methods to analyze the existence of stochastic resonance in such a bistable system. This is a first step toward the study of resonant phenomena in adsorbate systems with moving fronts and/or with presence of micro-reactors or spots. © 2012 Versita Warsaw and Springer-Verlag Wien.JAS thanks the MEC (Spain) for the award of a Collaboration fellowship.
