Zero-dispersion stochastic resonance

By N. G. Stocks, N. D. Stein, Stanislav M. Soskin and Peter V. E. McClintock

Abstract

A new form of stochastic resonance (SR), recently discovered in underdamped nonlinear oscillators for which the dependence of eigenfrequency upon energy has an extremum, is investigated. Its charaneristic features are identified and discussed on the basis of linear response theory and the fluctuation dissipation theorem. In common with conventional SR (in bistable Wlems), sharp increases in the nesponse to a weak periodic force, and in the signal/noise ratio, occur with increasing intensity of external noise (temperature) within a certain range. Unlike conventional SR, however, the dependence of the response on frequency is strongiy resonant
