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

Thermodynamics and Kinetics of a Brownian Motor
TL;DR: Fluctuation-driven transport is one mechanism by which chemical energy can directly drive the motion of particles and macromolecules and may find application in a wide variety of fields, including particle separation and the design of molecular motors and pumps.

Directional motion of brownian particles induced by a periodic asymmetric potential
TL;DR: The behaviour of colloidal particles suspended in solution and exposed to a sawtooth dielectric potential which is turned on and off periodically is studied, suggesting applications in separation processes for objects in the size range 0.1–5 μm and the analogy between the device and motor protein assemblies is pointed out.

Brownian motors
TL;DR: In this article, the authors present a proof-of-principle device, a diffusive temperature Brownian motor, which is particularly simple to implement experimentally in order to optimize and selectively control a rich variety of directed transport behaviors.
