Exploring the BEC-BCS Crossover with an Ultracold Gas of Li Atoms
M. Bartenstein, A. Altmeyer, S. Riedl +5
We present an overview of our recent measurements on the crossover from a Bose-Einstein condensate of molecules to a Bardeen-Cooper-Schrieffer superfluid. The experiments are perfo…
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…
Collective excitations of a degenerate gas at the BEC-BCS crossover
M. Bartenstein, A. Altmeyer, S. Riedl +4
We study collective excitation modes of a fermionic gas of Li atoms in the BEC-BCS crossover regime. While measurements of the axial compression mode in the cigar-shaped trap c…
Crossover from a molecular Bose-Einstein condensate to a degenerate Fermi gas
M. Bartenstein, A. Altmeyer, S. Riedl +4
We demonstrate a reversible conversion of a Li2 molecular Bose-Einstein condensate to a degenerate Fermi gas of atoms by adiabatically crossing a Feshbach resonance. By optical in…
