Phase-control of directed diffusion in a symmetric optical lattice

Author(s) : Schiavoni, Michele , Sanchez-Palencia, Laurent , Renzoni, Ferruccio , Grynberg, Gilbert
Description : We demonstrate the phenomenon of directed diffusion in a symmetric periodicpotential. This has been realized with cold atoms in a one-dimensionaldissipative optical lattice. The stochastic process of optical pumping leadsto a diffusive dynamics of the atoms through the periodic structure, while azer...
