Universal many-body response of heavy impurities coupled to a Fermi sea
Richard Schmidt, Michael Knap, Dmitri A. Ivanov +3
In this work we discuss the dynamical response of heavy quantum impurities immersed in a Fermi gas at zero and at finite temperature. Studying both the frequency and the time domai…
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…
