Rectifying fluctuations in an optical lattice
arXiv:cond-mat/0512551 · doi:10.1103/PhysRevLett.93.073904
Abstract
We have realized a Brownian motor by using cold atoms in a dissipative optical lattice as a model system. In our experiment the optical potential is spatially symmetric and the time-symmetry of the system is broken by applying appropriate zero-mean ac forces. We identify a regime of rectification of forces and a regime of rectification of fluctuations, the latter corresponding to the realization of a Brownian motor.
