Anisotropic excitation spectrum of a dipolar quantum Bose gas
G. Bismut, B. Laburthe-Tolra, E. Marechal +3
We measure the excitation spectrum of a dipolar Chromium Bose Einstein Condensate with Raman-Bragg spectroscopy. The energy spectrum depends on the orientation of the dipoles with…
Spontaneous demagnetization of a dipolar spinor Bose gas at ultra-low magnetic field
Benjamin Pasquiou, Etienne Maréchal, Gabriel Bismut +4
Quantum degenerate Bose gases with an internal degree of freedom, known as spinor condensates, are natural candidates to study the interplay between magnetism and superfluidity. In…
Spin relaxation and band excitation of a dipolar BEC in 2D optical lattices
B. Pasquiou, G. Bismut, E. Maréchal +4
We observe interband transitions mediated by the dipole-dipole interaction for an array of 1D quantum gases of chromium atoms, trapped in a 2D optical lattice. Interband transition…
Collective excitations of a dipolar Bose-Einstein condensate
G. Bismut, B. Pasquiou, E. Maréchal +4
We have measured the effect of dipole-dipole interactions on the frequency of a collective mode of a Bose-Einstein condensate. At relatively large numbers of atoms, the experimenta…
Optimized loading of an optical dipole trap for the production of Chromium BECs
G. Bismut, B. Pasquiou, D. Ciampini +4
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 o…
Control of dipolar relaxation in external fields
B. Pasquiou, G. Bismut, Q. Beaufils +6
We study dipolar relaxation in both ultra-cold thermal and Bose-condensed chromium atom gases. We show three different ways to control dipolar relaxation, making use of either a st…
