Biased diffusion in confined media: Test of the Fick-Jacobs approximation and validity criteria
P. S. Burada, G. Schmid, D. Reguera +2
We study biased, diffusive transport of Brownian particles through narrow, spatially periodic structures in which the motion is constrained in lateral directions. The problem is an…
Use and Abuse of a Fractional Fokker-Planck Dynamics for Time-Dependent Driving
E. Heinsalu, M. Patriarca, I. Goychuk +1
We investigate a subdiffusive, fractional Fokker-Planck dynamics occurring in time-varying potential landscapes and thereby disclose the failure of the fractional Fokker-Planck equ…
dc-biased stationary transport in the absence of dissipation
S. Denisov, S. Flach, P. Hanggi
We obtain stationary transport in a Hamiltonian system with ac driving in the presence of a dc bias. A particle in a periodic potential under the influence of a time-periodic field…
Brownian motors: current fluctuations and rectification efficiency
L. Machura, M. Kostur, P. Talkner +3
With this work we investigate an often neglected aspect of Brownian motor transport: The rôle of fluctuations of the noise-induced current and its consequences for the efficiency o…
