Abstract
We investigate quantum Brownian motion in adiabatically rocked ratchet systems. Above a crossover temperature T-c tunnelling events are rare, yet they already substantially enhance the classical particle current. Below T-c, quantum tunnelling prevails and the classical predictions grossly underestimate the transport. Upon approaching T=0 the quantum current exhibits a tunnelling induced reversal, and tends to a finite limit.
