As a model of Brownian motor, we consider the motion of particles in an asymmetric, single-well, periodic potential undergoing half-period shifts driven by two Poisson processes. Probability currents and stopping force are explicitly obtained as a function of the model parameters, and use of the notion of driving effective potential is made to bridge the present model with our previous works involving washboard potentials.

Abstract
As a model of Brownian motor, we consider the motion of particles in an asymmetric, single-well, periodic potential undergoing half-period shifts driven by two Poisson processes. Probability currents and stopping force are explicitly obtained as a function of the model parameters, and use of the notion of driving effective potential is made to bridge the present model with our previous works involving washboard potentials.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
