Stochastic resonance in a bistable potential is characterized as a syncronization effect of the hopping mechanism induced by the external periodic bias. Most notably, syncronization is shown i) to attain a maximum with increasing the forcing frequency close to the relevant switching rate, thus revealing a bonafide resonant process; ii) to occur even in the absence of symmetry breaking by the periodic forcing term.

Abstract
Stochastic resonance in a bistable potential is characterized as a syncronization effect of the hopping mechanism induced by the external periodic bias. Most notably, syncronization is shown i) to attain a maximum with increasing the forcing frequency close to the relevant switching rate, thus revealing a bonafide resonant process; ii) to occur even in the absence of symmetry breaking by the periodic forcing term.File in questo prodotto:
