    "abstract": "We demonstrate the phenomenon of directed diffusion in a symmetric periodic\npotential. This has been realized with cold atoms in a one-dimensional\ndissipative optical lattice. The stochastic process of optical pumping leads to\na diffusive dynamics of the atoms through the periodic structure, while a\nzero-mean force which breaks the temporal symmetry of the system is applied by\nphase-modulating one of the lattice beams. The atoms are set into directed\nmotion as a result of the breaking of the temporal symmetry of the system.",
