Abstract

The Langevin systems with a tilted periodic potential were discussed. A modulated system with a slowly varying potential was analyzed, to elucidate the physical meaning of the ratio of the diffusion constant to the differential mobility. By using a perturbation method, a large scale description of the probability density was derived for the modulated system. It was found that the ratio of the diffusion constant to the differential mobility, plays the role of the temperature in the large scale description of the system.
