The Current of Two Coupled Particles in Rocking Ratchet

Abstract

In this work, we come from the study of the current of the molecular motor, based on Langevin equation, this thesis investigates the current of two harmonically coupled particles moving in an asymmetry potential. We respectively discuss how the asymmetric rocking is the temporal asymmetric parameter affects the current of the rocking ratchet model show that it has the tight coupling property.
