Experiments on Critical Phenomena in a Noisy Exit Problem

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/153313We 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.4 pages, 5 figures, REVTEXData Analysis, Statistics and ProbabilityExperiments on Critical Phenomena in a Noisy Exit Problemtext
