Abstract
We analyze the atomic dynamics in an ac driven periodic optical potential which is symmetric in both time and space. We experimentally demonstrate that in the presence of dissipation the symmetry is broken, and a current of atoms through the optical lattice is generated as a result.Year: 2005 PMID： 16196778 DOI： 10.1103/PhysRevLett.95.073003
