主　　题：escape rate active Brownian particle rough potential effective potential 

摘      要：We discuss the escape problem with the consideration of both the activity of particles and the roughness of *** derive analytic expressions for the escape rate of an active Brownian particle in two types of rough potentials by employing the effective equilibrium approach and the Zwanzig *** find that activity enhances the escape rate,but both the oscillating perturbation and the random amplitude hinder escaping.
