Lifetime of angular momentum in a rotating strongly interacting Fermi gas
S. Riedl, E. R. Sanchez Guajardo, C. Kohstall +2
We investigate the lifetime of angular momentum in an ultracold strongly interacting Fermi gas, confined in a trap with controllable ellipticity. To determine the angular momentum…
Collective oscillations of a Fermi gas in the unitarity limit: Temperature effects and the role of pair correlations
S. Riedl, E. R. Sanchez Guajardo, C. Kohstall +6
We present detailed measurements of the frequency and damping of three different collective modes in an ultracold trapped Fermi gas of Li atoms with resonantly tuned interactio…
Finite-Temperature Collective Dynamics of a Fermi Gas in the BEC-BCS Crossover
M. J. Wright, S. Riedl, A. Altmeyer +4
We report on experimental studies on the collective behavior of a strongly interacting Fermi gas with tunable interactions and variable temperature. A scissors mode excitation in a…
Dynamics of a strongly interacting Fermi gas: the radial quadrupole mode
A. Altmeyer, S. Riedl, M. J. Wright +3
We report on measurements of an elementary surface mode in an ultracold, strongly interacting Fermi gas of 6Li atoms. The radial quadrupole mode allows us to probe hydrodynamic beh…
Note on "Collective Excitations of a Degenerate Gas at the BEC-BCS Crossover", Phys. Rev. Lett. 92, 203201 (2004)
A. Altmeyer, S. Riedl, C. Kohstall +3
We present a reinterpretation of our previous results on the radial compression mode of a degenerate quantum gas in the BEC-BCS crossover in [1]. We show that our former data are c…
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…
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…
