Diffusion and Current of Brownian Particles in Tilted Piecewise Linear Potentials: Amplification and Coherence
Els Heinsalu, Risto Tammelo, Teet Ord
Overdamped motion of Brownian particles in tilted piecewise linear periodic potentials is considered. Explicit algebraic expressions for the diffusion coefficient, current, and coh…

On the amplification of diffusion on piecewise linear potentails by direct current
Els Heinsalu, Risto Tammelo, Teet Ord
The diffusive motion of overdamped Brownian particles in tilted piecewise linear pontentials is considered. It is shown that the enhancement of diffusion coefficient by an external…
