Observation of dipole-dipole interaction in a degenerate quantum gas
J. Stuhler, A. Griesmaier, T. Koch +5
We have investigated the expansion of a Bose-Einstein condensate (BEC) of strongly magnetic chromium atoms. The long-range and anisotropic magnetic dipole-dipole interaction leads…
High Resolution Rydberg Spectroscopy of ultracold Rubidium Atoms
Axel Grabowski, Rolf Heidemann, Robert Löw +2
We present experiments on two-photon excitation of Rb atoms to Rydberg states. For this purpose, two continuous-wave (cw)-laser systems for both 780 nm and 480 nm have…
Production of a chromium Bose-Einstein condensate
Axel Griesmaier, Jürgen Stuhler, Tilman Pfau
The recent achievement of Bose-Einstein condensation of chromium atoms [1] has opened longed-for experimental access to a degenerate quantum gas with long-range and anisotropic int…
Depolarisation cooling of an atomic cloud
S. Hensler, A. Greiner, J. Stuhler +1
We propose a cooling scheme based on depolarisation of a polarised cloud of trapped atoms. Similar to adiabatic demagnetisation, we suggest to use the coupling between the internal…
Bose-Einstein condensation of chromium
Axel Griesmaier, Jörg Werner, Sven Hensler +2
We report on the generation of a Bose-Einstein condensate in a gas of chromium atoms, which will make studies of the effects of anisotropic long-range interactions in degenerate qu…
