Structured noise induced non-recross barrier escaping

Abstract

The time-dependent barrier passage of a particle driven by the structured noise is studied in the field of a metastable potential. Quantities such as the probability of passing over the saddle point and transmission coefficient of the escaping rate are calculated for a thimbleful of insight into the diffusion dynamical properties. Results show that the barrier recrossing behavior is greatly reduced by the structured noisy environment. Particles diffusion in such an dissipative environment tends to successfully escape from the potential well without any embarrassments.
