Breathing Mode of a BEC Repulsively Interacting with a Fermionic Reservoir
Bo Huang, Isabella Fritsche, Rianne S. Lous +4
We investigate the fundamental breathing mode of a small-sized elongated Bose-Einstein condensate coupled to a large Fermi sea of atoms. Our observations show a dramatic shift of t…
Thermometry of a deeply degenerate Fermi gas with a Bose-Einstein condensate
Rianne S. Lous, Isabella Fritsche, Michael Jag +2
We measure the temperature of a deeply degenerate Fermi gas, by using a weakly interacting sample of heavier bosonic atoms as a probe. This thermometry method relies on the thermal…
Lifetime of Feshbach dimers in a Fermi-Fermi mixture of Li and K
Michael Jag, Marko Cetina, Rianne S. Lous +3
We present a joint experimental and theoretical investigation of the lifetime of weakly bound dimers formed near narrow interspecies Feshbach resonances in mass-imbalanced Fermi-Fe…
Ultrafast many-body interferometry of impurities coupled to a Fermi sea
M. Cetina, M. Jag, R. S. Lous +8
The fastest possible collective response of a quantum many-body system is related to its excitations at the highest possible energy. In condensed-matter systems, the corresponding…
Decoherence of Impurities in a Fermi Sea of Ultracold Atoms
Marko Cetina, Michael Jag, Rianne S. Lous +4
We investigate the decoherence of K impurities interacting with a three-dimensional Fermi sea of Li across an interspecies Feshbach resonance. The decoherence is measu…
Observation of a Strong Atom-Dimer Attraction in a Mass-Imbalanced Fermi-Fermi Mixture
Michael Jag, Matteo Zaccanti, Marko Cetina +5
We investigate a mixture of ultracold fermionic K atoms and weakly bound LiK dimers on the repulsive side of a heteronuclear atomic Feshbach resonance. By radio…
