A"Burnt Bridge'' Brownian Ratchet

Motivated by a biased diffusion of molecular motors with the bias dependent on the state of the substrate, we investigate a random walk on a one-dimensional lattice that contains weak links (called " bridges ") which are affected by the walker. Namely, a bridge is destroyed with probability p when the walker crosses it; the walker is not allowed to cross it again and this leads to a directed mo...

Minimal Brownian ratchet: an exactly solvable model.

We develop an analytically solvable three-state discrete-time minimal Brownian ratchet (MBR), where the transition probabilities between states are asymmetric. By solving the master equations, we obtain the steady-state probabilities. Generally, the steady-state solution does not display detailed balance, giving rise to an induced directional motion in the MBR. For a reduced two-dimensional par...

The flashing Brownian ratchet and Parrondo’s paradox

A Brownian ratchet is a one-dimensional diffusion process that drifts towards a minimum of a periodic asymmetric sawtooth potential. A flashing Brownian ratchet is a process that alternates between two regimes, a one-dimensional Brownian motion and a Brownian ratchet, producing directed motion. These processes have been of interest to physicists and biologists for nearly 25 years. The flashing ...

A MEMS implementation of a Brownian Ratchet

A Brownian Ratchet is a device that can rectify the random Brownian motion of particles to yield a directed steady-state flow. We can imagine a thermo-fluid field of particles which interact with the ratchet. The laws of thermodynamics imply that the ratchet must use energy from some other source. The dynamics of continuous-time Brownian ratchets are determined by a stochastic partial different...
