TLDR
In this paper, the authors considered a Brownian particle in a periodic potential under heavy damping and showed that if the particle is subject to an external force having time correlations, detailed balance is lost and the particle can exhibit a nonzero net drift speed.
Abstract
We consider a Brownian particle in a periodic potential under heavy damping. The second law forbids it from displaying any net drift speed, even if the symmetry of the potential is broken. But if the particle is subject to an external force having time correlations, detailed balance is lost and the particle can exhibit a nonzero net drift speed. Thus, broken symmetry and time correlations are sufficient ingredients for transport.

Current transport for a spatially periodic potential system with color noises

TL;DR: In this paper, the transport of an underdamped particle driven by an external force in a periodic asymmetric potential with color noises is investigated and the corresponding mathematical model is established.

Multi Player Parrondo Games with Rigid Coupling

TL;DR: In this paper , a strong coupling between the player such that the gain or loss of all players in one round is the same is introduced, and the dependency of the gain on the various parameters of the games is determined.

Rectifying effect in a Josephson junction ratchet array

TL;DR: In this article, the authors studied numerically a rectifying effect in an underdamped Josephson junction ratchet array driven by dc and ac current, where the guide banks of high critical currents are assigned for all the longitudinal junctions to prevent the percolative pattern of vortex motion.

Approximation to a Fokker-Planck equation for the Brownian motor

Ryo Ikota
- 06 Jun 2018 - 
TL;DR: An approximate method is proposed and numerically confirmed for a time-dependent Fokker-Planck equation (FPE) modeling the Brownian motor and it is found to be reduced to an ordinary differential equation.
