摘要：
The transport phenomenon(directional movement) of self-propelled Brownian particles moving in a smooth corrugated confined channel with transverse force and colored noise is investigated. The direction of the transport changes several times with increasing transverse force amplitude. For different values of the transverse force amplitude, the x component noise has different influences on the transport phenomenon. y component noise has a negligible effect on the x directional movement. Interestingly, the average velocity demonstrates complex behavior with increasing self-propelled speed. (C) 2019 Published by Elsevier B.V.
