A new model of geometry-induced stochastic resonance

Abstract

We propose a new model where entropic stochastic resonance and geometric stochastic resonance can both be observed by controlling the geometry parameters and the external force. Such stochastic resonance manifests a more adjustable character in small-scale systems where confinement and noise play a prominent role. The magnitude of the effect is sensitive to the geometry modification, thus leading to various resonance conditions. The novel phenomenon found could thus be beneficial for the control of the basic properties in these systems.
