Asymmetric Effects on Escape Rates of Bistable System

Asymmetric Effects on Escape Rates of Bistable System

The asymmetric effects on the escape rates from the stable states x＋ in the bistable system are analyzed. The results indicate that the multiplicative noise and the additive noise always enhance the particle escape from stable states x~ of bistable. However, the asymmetric parameter r enhances the p...

Zusammenfassung:The asymmetric effects on the escape rates from the stable states x＋ in the bistable system are analyzed. The results indicate that the multiplicative noise and the additive noise always enhance the particle escape from stable states x~ of bistable. However, the asymmetric parameter r enhances the particle escape from stable state x＋, and holds back the particle escape from stable state x_.
