Abstract
A numerical algorithm is implemented so as to explore brownian particle diffusion in a periodic potential throughout the full viscosity range. The predictions of the theory of activated processes are checked. In particular, a recent refinement of the vanishingly small viscosity limit of the Kramers approach by Büttiker et al. (Phys. Rev. B28 1268 (1983)) is found to fit better our numerical results.
