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.read more

Emergent Flows, Irreversibility and Unsteady Effects in Asymmetric and Looped Geometries
TL;DR: In this article, the authors explore two general ways of how rectified flows emerge in macro-fluidic networks as a consequence of irreversibility and unsteady effects: when branches or channels of a network have asymmetric internal geometry and when a network contains loops.

Physics of free climbing.
TL;DR: In this article, it is shown that there is a discrete set of favorable rope lengths assuring the shortest climbing times, as they correspond to local minima of mean first-passage time.
Carnot, Stirling, Ericsson stochastic heat engines: Efficiency at maximum power
TL;DR: In this article , a mesoscopic engine with a Brownian particle trapped by an optical tweezers is considered and the dynamics of this engine is described as an overdamped Langevin equation with a harmonic potential, whereas is in contact with two thermal baths at different temperatures.

The Fokker-Planck Equation: Methods of Solution and Applications
TL;DR: In this paper, the Fokker-Planck Equation for N Variables (FPE) was extended to N = 1 variable and N = 2 variables, where N is the number of variables in the system.
