Collective spin modes of a trapped quantum ferrofluid
S. Lepoutre, L. Gabardos, K. Kechadi +5
We report on the observation of a collective spin mode in a spinor Bose-Einstein condensate. Initially, all spins point perpendicular to the external magnetic field. The lowest ene…
Dipolar atomic spin ensembles in a double-well potential
A. de Paz, B. Naylor, J. Huckans A. Carrance +5
We experimentally study the spin dynamics of mesoscopic ensembles of ultracold magnetic spin-3 atoms located in two separated wells of an optical dipole trap. We use a radio-freque…
Resonant demagnetization of a dipolar BEC in a 3D optical lattice
A. de Paz, A. Chotia, E. Marechal +4
We study dipolar relaxation of a chromium BEC loaded into a 3D optical lattice. We observe dipolar relaxation resonances when the magnetic energy released during the inelastic coll…
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…
Thermodynamics of a Bose Einstein condensate with free magnetization
B. Pasquiou, E. Marechal, L. Vernac +2
We study thermodynamic properties of a gas of spin 3 52Cr atoms across Bose Einstein condensation. Magnetization is free, due to dipole-dipole interactions (DDIs). We show that the…
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…
