The motion of a particle in a correlated random potential under the influence of a driving force is investigated in mean field theory. The correlations of the disorder are characterized by a short distance cutoff and a power law decay with exponent γ at large distances. Depending on temperature and γ , drift with finite mobility , creep or pinning is found. This is in qualitative agreement with...
