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…
Dynamical frictional phenomena in an incommensurate two-chain model
Takaaki Kawaguchi, Hiroshi Matsukawa
Dynamical frictional phenomena are studied theoretically in a two-chain model with incommensurate structure. A perturbation theory with respect to the interchain interaction reveal…
Static and dynamic properties of frictional phenomena in a one-dimensional system with randomness
Takaaki Kawaguchi, Hiroshi Matsukawa
Static and dynamic frictional phenomena at the interface with random impurities are investigated in a two-chain model with incommensurate structure. Static frictional force is caus…
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…
