Exploring emergent heterogeneous phases in strongly repulsive Fermi gases
F. Scazza, G. Valtolina, A. Amico +5
Recent experiments have revitalized the interest in a Fermi gas of ultracold atoms with strong repulsive interactions. In spite of its seeming simplicity, this system exhibits a co…
Time-resolved observation of competing attractive and repulsive short-range correlations in strongly interacting Fermi gases
A. Amico, F. Scazza, G. Valtolina +5
We exploit a time-resolved pump-probe spectroscopic technique to study the out-of-equilibrium dynamics of an ultracold two-component Fermi gas, selectively quenched to strong repul…
Connecting dissipation and phase slips in a Josephson junction between fermionic superfluids
A. Burchianti, F. Scazza, A. Amico +6
We study the emergence of dissipation in an atomic Josephson junction between weakly-coupled superfluid Fermi gases. We find that vortex-induced phase slippage is the dominant micr…
Repulsive Fermi polarons in a resonant mixture of ultracold Li atoms
F. Scazza, G. Valtolina, P. Massignan +7
We employ radio-frequency spectroscopy to investigate a polarized spin-mixture of ultracold Li atoms close to a broad Feshbach scattering resonance. Focusing on the regime of…
Exploring the ferromagnetic behaviour of a repulsive Fermi gas via spin dynamics
G. Valtolina, F. Scazza, A. Amico +6
Ferromagnetism is a manifestation of strong repulsive interactions between itinerant fermions in condensed matter. Whether short-ranged repulsion alone is sufficient to stabilize f…
Josephson effect in fermionic superfluids across the BEC-BCS crossover
G. Valtolina, A. Burchianti, A. Amico +8
We report on the observation of the Josephson effect between two strongly interacting fermionic superfluids coupled through a thin tunneling barrier. We prove that the relative pop…
