Abstract

We study the problem of activated escape of a particle from a potential well when it is subjected to a periodic force of high frequency. We focus on the result that on time scales larger than the period of perturbation, the dynamics is equivalent to one in which the periodic perturbation is replaced by a time independent effective potential. A derivation of this result from the Langevin dynamics point of view is provided. Finally, predictions of the theory are tested against numerical results and excellent agreement is found.
