Physical review letters, 2005•APSWe 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 interferometer and a ring interferometer.
