Transport of Coupled Self-propelled Particles with Gaussian Colored Noise
Abstract
The transport of coupled self-propelled particles with colored noise and potential is investigated. Large translational motion noise intensity is good for the transport in direction, but large self-correlation time of translational motion noise will inhibit this transport. For proper value of the asymmetry parameter, coupled passive particles move always in direction with increasing angle noise intensity, but coupled self-propelled particles appear the transport reverse phenomenon with increasing angle noise intensity. Large length of the spring is good for the directional transport. The average velocity has a maximum and a minimum with increasing spring constant . For passive and very small self-propelled speed coupled particles, large number of particle is good for directional movement, but the effect of coupling will become weak when the self-propelled speed is large.
