Dissipation Enhanced Asymmetric Transport in Quantum Ratchets
Gen Tatara, Macoto Kikuchi, Satoshi Yukawa +1
Quantum mechanical motion of a particle in a periodic asymmetric potential is studied theoretically at zero temperature. It is shown based on semi-classical approximation that the…

Quantum Ratchets
Satoshi Yukawa, Macoto Kikuchi, Gen Tatara +1
The concept of thermal ratchets is extended to the system governed by quantum mechanics. We study a tight-binding model with an asymmetric periodic potential contacting with a heat…
