A new mechanism of hypersensitive transport in tilted sharp ratchets induced by noise flatness
Romi Mankin, Astrid Haljas, Risto Tammelo +1

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…
