An optical clock with neutral atoms confined in a shallow trap

Author(s) : Lemonde, Pierre , Wolf, Peter
Description : We study the trap depth requirement for the realization of an optical clock using atoms confined in a lattice. We show that site-to-site tunnelling leads to a residual sensitivity to the atom dynamics hence requiring large depths ($50$ to $100\\,E_r$ for Sr) to avoid any frequency shift or line broa...

Non-Gaussian Velocity Distributions in Optical Lattices

Author(s) : Jersblad, Johan , Ellmann, Harald , Stöchkel, Kristian , Kastberg, Anders , Sanchez-Palencia, Laurent , Kaiser, Robin
Description : We present a detailed experimental study of the velocity distribution of atoms cooled in an optical lattice. Our results are supported by full-quantum numerical simulations. Even though the Sisyphus effect, the responsible cooling mechanism, has been used extensively in many cold atom experiments, n...

Photon-assisted tunneling in optical lattices: Ballistic transport of interacting boson pairs

Author(s) : Weiss, Christoph , Breuer, Heinz-Peter
Description : In a recent experiment [PRL 100, 040404 (2008)] an analog of photon-assisted tunneling has been observed for a Bose-Einstein condensate in an optical lattice subject to a constant force plus a sinusoidal shaking. Contrary to previous theoretical predictions, the width of the condensate was measured ...
