title: Mechanical and Langevin thermostats: Gulton staircase problem.
abstract: Dynamics in a Gulton staircase is considered based on a model in which many particles, coupled through an average velocity, are in contact with a Gaussian thermostat. Computer simulation gives information on entropy production, the stationary mass current, and distribution functions of both particle positions and momenta. A Langevin thermostat is also considered for the sake of comparison with a mechanical thermostat.
