Stochastic resonance in deformable potential with time-delayed feedback

This paper reports the stochastic resonance (SR) phenomenon with memory effects for a Brownian particle in potential whose shape is subjected to deformation. We model deformation system by Remoissenet–Peyrard and time-delayed feedback. The question of possible influence feedback on occurrence SR then our interest. examine numerically effect strength as well time delay terms hysteresis loop area. It found that has significant can induce double resonances system. show properties are varying, depending interdependence between strength, parameter. article part theme issue ‘Vibrational driven nonlinear systems (part 1)’.
