Correlation between diffusion and coherence in Brownian motion on a tilted periodic potential

The paper studies the overdamped motion of Brownian particles in a tilted saw-tooth potential. The dependencies of the diffusion coefficient and coherence level of Brownian transport on temperature, tilting force, and the shape of the potential are analyzed. It is demonstrated that at low temperatures the coherence level of Brow-nian transport stabilizes in… CONTINUE READING
