Entropic stochastic resonance induced by a transverse driving force

The phenomenon of entropic stochastic resonance (ESR) is investigated with the presence a time-periodic force in transverse direction. Simulation results manifest that ESR can survive even if there no static bias any direction, just driving field applied. In weak noise region, leads to giant-suppression escape rate from one well another, i.e. trapping. increase intensity will eliminate this suppression and induce phenomenon. An alternative quantity, called mean free flying time, also proposed characterize as conventional spectral power amplification. be modulated conveniently by periodic force, which implies an method for controlling dynamics small-scale systems.
