Ultracold Feshbach Molecules
Francesca Ferlaino, Steven Knoop, Rudolf Grimm
In this Chapter, we give an introduction into experiments with Feshbach molecules and their applications. In particular, we discuss the various creation and detection methods, and…
Collisions between tunable halo dimers: exploring an elementary four-body process with identical bosons
F. Ferlaino, S. Knoop, M. Mark +4
We study inelastic collisions in a pure, trapped sample of Feshbach molecules made of bosonic cesium atoms in the quantum halo regime. We measure the relaxation rate coefficient fo…
`Stückelberg interferometry' with ultracold molecules
M. Mark, T. Kraemer, P. Waldburger +4
We report on the realization of a time-domain `Stückelberg interferometer', which is based on the internal state structure of ultracold Feshbach molecules. Two subsequent passages…
Ultracold Fermi gases in the BEC-BCS crossover: a review from the Innsbruck perspective
Rudolf Grimm
A review of recent BEC-BCS crossover experiments in ultracold Fermi gases is given with particular emphasis on the work performed with lithium-6 at the University of Innsbruck.
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…
