Experiments on Critical Phenomena in a Noisy Exit Problem

By D. G. Luchinsky, R. S. Maier, R. Mannella, P. V. E. McClintock and D. L. Stein

Abstract

SUMMARY We consider noise-driven exit from a domain of attraction in a two-dimensional bistable system lacking detailed balance. Through analog and digital stochastic simulations, we find a theoretically predicted bifurcation of the most probable exit path as the parameters of the system are changed, and a corresponding nonanalyticity of the activation energy. We also investigate the extent to which the bifurcation is related to the local breaking of time-reversal invariance
