Effects of self-propulsion, chirality and noise-correlation on the entropic stochastic resonance of an active Brownian particle

Abstract

Entropic stochastic resonance (ESR) of an active Brownian particle (ABP) confined in two kinds of 2D cavities is investigated. The chirality and self-propulsion, which represent two vital characteristic features of the ABP, can enhance and suppress the ESR monotonously. Novelty, in the absence of the translational noises, the ESR can be induced by the rotational noise solely on condition that the rotational frequency is large enough. Moreover, the ESR can be detected more easily with increasing noise-correlation. This research is expected to provide a theoretical basis for controlling the ABP in confined spaces.
