Query: Interacting particles in a periodically moving potential: Traveling wave
  and transport   We study a system of interacting particles in a periodically moving external
potential, within the simplest possible description of paradigmatic symmetric
exclusion process on a ring. The model describes diffusion of hardcore
particles where the diffusion dynamics is locally modified at a uniformly
moving defect site, mimicking the effect of the periodically moving external
potential. The model, though simple, exhibits remarkably rich features in
particle transport, such as polarity reversal and double peaks in particle
current upon variation of defect velocity and particle density. By tuning these
variables, the most efficient transport can be achieved in either direction
along the ring. These features can be understood in terms of a traveling
density wave propagating in the system. Our results could be experimentally
tested, e.g., in a system of colloidal particles driven by a moving optical
tweezer.
