| Decoherence Driven Quantum Transport (2005) | |||||||||
Abstract | |||||||||
| We propose a new mechanism to generate a dc current of particles at zero bias based on a noble interplay between coherence and decoherence. We show that a dc current arises if the transport process in one direction is maintained coherent while the process in the opposite direction is incoherent. We provide possible implementations of the idea using an atomic Michelson and an atomic Aharonov-Bohm interferometer.. Comment: 4 pages, 3 figures | |||||||||
