Brownian motion in a complex asymmetric periodic potential under colored-noise action
Brownian motion in a complex asymmetric periodic potential under colored-noise action is studied. Two colored noises are investigated, namely the ``red'' noise ( the Ornstein-Uhlenbeck process) and the wideband colored noise (``green'' noise) , which is equal to the time derivative of the ``red'' noise. the impact of the ``green'' noise is essential for small size structures (when the size of structure under consideration is of the order of the wavelength of the low frequency oscillators of the phonon field).
