DY 10: Internal Symposium: Controlling Dirty Bosons: Disorder Effects on BECs

DY 10.1: Invited Talk

Tuesday, February 26, 2008, 09:30–10:00, MA 001

Localization of interacting ultra cold atoms in a disordered potential — •Alain Aspect1, David Clément1, Pierre Lugan1, Philippe Bouyer2, Gora Shlyapnikov1, and Laurent Sanchez-Palencia11Institut d'Optique, Palaiseau, France — 2LPTMS, Orsay, France

Ultra cold atoms can be placed in disordered potentials produced by laser speckle. Such a correlated potential is very well mastered on the experimental side, and perfectly characterized so that relevant theoretical treatments can be developped. It is a useful toy model to study Anderson localization, and test the influence of interactions.

We will present experimental and theoretical results on 1D localization for a Bose Einstein Condensate placed in a laser speckle disordered potential, as a function of relevant parameters: amplitude and correlation length of the disordered potential, healing length of the BEC...
