Structured noise induced non-recross barrier escaping

TL;DR

This paper investigates how structured noise influences particle escape over a potential barrier, showing that such noise reduces recrossing and enhances escape probability in metastable systems.

Contribution

It introduces a detailed analysis of barrier crossing dynamics under structured noise, revealing its role in suppressing recrossings and facilitating escape.

Findings

Structured noise significantly reduces barrier recrossing.

Particles are more likely to escape successfully in structured noisy environments.

The study provides insights into diffusion dynamics in dissipative systems.

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.
