Bose-Einstein Condensate in Optical Lattices



A Browaeys, James V. Porto, S P. Peil, B Laburthe, J Obrecht, C R. McKenzie


We will present some results from the two Bose-Einstein condensation experiments at NIST Gaithersburg (on sodium and rubidium). We investigate the behaviour of the condensate in an optical lattice. The lattices are created by illuminating the cloud with the interference pattern created by two laser beams. This creates a periodic potential acting on the atoms, allowing a description of the system in terms of band structure theory. In a first set of experiments we analyzed the loading of the condensate into a 1 D lattice as well as in a super lattice in which two spatial periods are present. We then accelerate the lattice in order to observe the Bloch oscillations. We finally investigate the coherence properties of the cloud.
