Collective excitations of a dipolar Bose-Einstein condensate
We have measured the effect of dipole-dipole interactions on the frequency of a collective mode of a Bose-Einstein condensate.

Optimized loading of an optical dipole trap for the production of chromium BECs
We report on a strategy to maximize the number of chromium atoms transferred from a magneto-optical trap into an optical trap through accumulation in metastable states via strong optical pumping.

Collective excitations in a dipolar Bose-Einstein condensate
Control of dipolar relaxation in external fields
We study dipolar relaxation in both ultracold thermal and Bose-condensed Cr atom gases. We show three different ways to control dipolar relaxation, making use of either a static magnetic field, an oscillatory magnetic field, or an optical lattice to reduce the dimensionality of the gas from three-dimensional (3D) to two-dimensional (2D).

Condensation de Bose-Einstein du chrome
French version: Condensation de Bose-Einstein du chrome A cause de son fort moment magnétique dans l’état fondamental, le chrome est un bon candidat pour l’étude des interactions dipolaires dans un gaz dégénéré. Nous avons mis en place un dispositif expérimental…
