Abstract
We present the exact solution of the Fokker-Planck equation for a particle escaping from the square-well potential under the influence of white noise. The mean-square displacement obeys the Einstein relation, in contrast to the conclusion of the recent article by Akio Morita [Phys. Rev. E 49, 3697 (1994)].
