Out-of-equilibrium dynamics of strongly correlated Fermi gases of ultracold atoms

Abstract
Strongly correlated Fermi systems exhibit remarkable physical properties resulting from the interplay of interactions, statistics and dimensionality, with promising prospects for technological applications. The fine control of interactions and optical trapping potentials in ultracold atomic ensembles provides unique opportunities to explore strong correlation phenomena, such as superfluidity and magnetism. In our experiment at LENS, we produce lithium-6 degenerate Fermi gases in the vicinity of a broad Feshbach resonance, allowing an ultimate control over the inter-atomic interactions. By imprinting high-resolution optical potentials and through the fast coherent control of the internal atomic degrees of freedom, we investigate the out-of-equilibrium dynamics of strongly interacting Fermi gases. In this talk, I will discuss some recent results on the competition between dissipation and Josephson dynamics of fermionic superfluids through a weak link, and on the spectroscopic study of the growth of correlations in Fermi gases quenched to strong repulsion.
