Abstract

The average velocity of self-propelled particles in a two-dimensional potential with colored noise is investigated. The current reversal phenomenon appear with changing x direction colored noise intensity. There exist optimal values of the parameters at which the average velocity takes its maximal value. The y direction noise and the self-propelled angle noise have great effects on the x direction average velocity, but they can not induce x direction particles transport phenomenon themselves.
