Production of strongly bound 39K bright solitons
S Lepoutre, L Fouché, A Boissé +4
We report on the production of 39 K matter-wave bright solitons, i.e., 1D matter-waves that propagate without dispersion thanks to attractive interactions. The volume of the solito…
Feedback control of trapped coherent atomic ensembles
T. Vanderbruggen, R. Kohlhaas, A. Bertoldi +4
We demonstrate how to use feedback to control the internal states of trapped coherent ensembles of two-level atoms, and to protect a superposition state against the decoherence ind…
Specular reflection of matter waves from a rough mirror
V. Savalli, D. Stevens, J. Esteve +4
We have made a high resolution study of the specularity of the atomic reflection from an evanescent wave mirror using velocity selective Raman transitions. We have observed a doubl…
Thermalization of magnetically trapped metastable helium
A. Browaeys, A. Robert, O. Sirjean +5
We have observed thermalization by elastic collisions of magnetically trapped metastable helium atoms. Our method directly samples the reconstruction of a thermal energy distributi…
Quasi-continuous atom laser in the presence of gravity
F. Gerbier, P. Bouyer, A. Aspect
We analyse the extraction of a coherent atomic beam from a trapped Bose-Einstein condensate using a rf transition to a non-trapping state at T=0 K. Our quantum treatment fully take…
Multi frequency evaporative cooling to BEC in a high magnetic field
V. Boyer, S. Murdoch, Y. Le Coq +3
We demonstrate a way to circumvent the interruption of evaporative cooling observed at high bias field for Rb atoms trapped in the (F=2, m=+2) ground state. Our scheme uses…
