Ultracold Molecules in the Ro-Vibrational Triplet Ground State
F. Lang, K. Winkler, C. Strauss +2
We report here on the production of an ultracold gas of tightly bound Rb2 molecules in the ro-vibrational triplet ground state, close to quantum degeneracy. This is achieved by opt…
Coherent optical transfer of Feshbach molecules to a lower vibrational state
K. Winkler, F. Lang, G. Thalhammer +3
Using the technique of stimulated Raman adiabatic passage (STIRAP) we have coherently transferred ultracold 87Rb2 Feshbach molecules into a more deeply bound vibrational quantum le…
Precision Measurements of Collective Oscillations in the BEC-BCS Crossover
A. Altmeyer, S. Riedl, C. Kohstall +6
We report on precision measurements of the frequency of the radial compression mode in a strongly interacting, optically trapped Fermi gas of Li-6 atoms. Our results allow for a te…
Atom-molecule dark states in a Bose-Einstein condensate
K. Winkler, G. Thalhammer, M. Theis +3
We have created a dark quantum superposition state of a Rb Bose-Einstein condensate (BEC) and a degenerate gas of Rb ground state molecules in a specific ro-vibrational state u…
Precise determination of Li cold collision parameters by radio-frequency spectroscopy on weakly bound molecules
M. Bartenstein, A. Altmeyer, S. Riedl +9
We employ radio-frequency spectroscopy on weakly bound Li molecules to precisely determine the molecular binding energies and the energy splittings between molecular states…
Tuning the scattering length with an optically induced Feshbach resonance
M. Theis, G. Thalhammer, K. Winkler +4
We demonstrate optical tuning of the scattering length in a Bose-Einstein condensate as predicted by Fedichev {\em et al.} [Phys. Rev. Lett. {\bf 77}, 2913 (1996)]. In our experime…
