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

Stasis domains and slip surfaces in the locomotion of a bio-inspired two-segment crawler
Paolo Gidoni,Antonio DeSimone +1 more
TL;DR: In this article, the authors formulate and solve the locomotion problem for a bio-inspired crawler consisting of two active elastic segments (i.e., capable of changing their rest lengths), resting on three supports providing directional frictional interactions.

Phase synchronization for two Brownian motors with bistable coupling on a ratchet
TL;DR: In this paper, the authors studied phase synchronization for a walker on a ratchet potential, and established a connection between optimal transport in ratchets and the phenomenon of phase synchronization through Arnold tongues.

Physics and Life
TL;DR: In this paper, the molecular basis of the living cell was revealed and a solution to both the nature and the origin of life would soon be found, inspired by Erwin Schrodinger's book What is Life? (1944).

A chemically driven fluctuating ratchet model for actomyosin interaction.
TL;DR: In this article, a Brownian motor of fluctuating ratchet kind was designed with the aim to describe the interaction between a Myosin II head and a neighboring actin filament. But the motor was not designed for the actomyosin interaction.
