Spin response and metastability of a strongly repulsive Fermi gas of ultracold atoms

Andrea Amico, Francesco Scazza, Giacomo Valtolina +6 more

Ultracold atomic Fermi gases close to Feshbach resonances represent the ideal platform to study strongly correlated fermionic states [1]. Up to now, most of the experimental efforts have been dedicated to the study of the famous BEC-BCS crossover, i.e. the transition from a Bose-Einstein condensate of tightly bound molecules to a BCS superfluid of long-range fermion pairs. However, such fermionic gases are the ideal environment to explore also the effects of strong, repulsive interactions. The interest in studying repulsive Fermi gases is manifold, since many phase transitions are driven by the strong repulsion between electrons in solids. One notable example is represented by the onset of itinerant ferromagnetism in metals, as envisioned by Stoner almost ninety years ago.

Exploring emergent heterogeneous phases in strongly repulsive Fermi gases

An experimental study of a Fermi gas of ultracold atoms with strong repulsive interactions leads to the discovery of an emulsion state of anticorrelated fermions and pairs. This finding allows exploration of quantum emulsions and also possibly of inhomogeneous superfluid regimes.

Repulsive dynamics of strongly attractive one-dimensional quantum gases

Maciej Łebek, Andrzej Syrwid, Piotr T. Grochowski +1 more

We analyze the dynamics of one-dimensional quantum gases with strongly attractive contact interactions. We specify a class of initial states for which attractive forces effectively act as strongly repulsive ones during the time evolution. Our findings extend the theoretical results on the super-Tonks-Girardeau gas to a highly nonequilibrium dynamics. The mechanism is illustrated on the prototypical problem of the domain stability in a two-component Fermi gas. We also discuss finite-range interactions and analyze the universality of the presented results. Moreover, we use our conclusions to argue for the existence of metastable quantum droplets in the regime of strongly attractive contact and attractive dipolar interactions.
