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

Energy transformation in biological molecular motors
TL;DR: The principle of rectified thermal diffusion has recently received a great support from the single-molecule studies as discussed by the authors, and a few specific motor systems are considered to illustrate the general principle.

The loose coupling mechanism in molecular machines of living cells.
TL;DR: The long‐distance multistep sliding of a single myosin head on an actin filament, coupled with the hydrolysis of one ATP molecule, was observed by Yanagida's group using highly developed techniques of optical microscopy and micromanipulation, giving direct evidence for the loose coupling between the chemical reaction and the mechanical event in the sliding machine.

TL;DR: It is shown that the escape probabilities can be changed very strongly even by a comparatively weak force, and the logarithmic susceptibility, which is analyzed theoretically and through analog and digital simulations, is described.
