Collective particle transport in a peristaltic ratchet system
Original language description
We consider particles with repulsive nearest-neighbor interactions in a periodically modulated tilted-sine potential as a model for a peristaltic ratchet system. Using the Markov chain approach to kinetics (MCAK), the collective transport behavior is investigated with respect to the modulation period, interaction strength, and applied mechanical bias (tilt amplitude). In the stationary state, a maximum is found in the period-averaged particle current and transport efficiency as function of both the mechanical bias and the modulation period. The efficiency can be enhanced when the interaction strength is increased. While the maximal current arises for fast modulation, maximum efficiency is obtained for comparatively slow modulation.
