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…

Polarons, Dressed Molecules, and Itinerant Ferromagnetism in ultracold Fermi gases
Pietro Massignan, Matteo Zaccanti, Georg M. Bruun
In this review, we discuss the properties of a few impurity atoms immersed in a gas of ultracold fermions, the so-called Fermi polaron problem. On one side, this many-body system i…
