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

Flashing subdiffusive ratchets in viscoelastic media
Vasyl O. Kharchenko,Igor Goychuk +1 more
TL;DR: In this paper, the central Brownian particle is elastically coupled to surrounding auxiliary Brownian quasi-particles which account for the influence of viscoelastic environment, and the external force influences only the motion of central particle not affecting directly the environmental degrees of freedom.

Directed motion of Brownian particles with internal energy depot
TL;DR: In this article, a model of Brownian particles with the ability to take up energy from the environment, to store it in an internal depot, and to convert internal energy into kinetic energy of motion is discussed.

The flow of a reversible ratchet
TL;DR: In a certain process, the behavior of the particle flow in two potential parameters is studied and then it is found that structures exist in the net flow of particles in different potentials or processes.

Operation of theoretical Brownian motors based on morphological adaptations
TL;DR: In this paper, the dynamics of autonomous Brownian motors that achieve rectified motion due to morphological changes is analyzed, and the effects of hydrodynamic interactions are quantified as function of the morphological asymmetry.
