Non-equilibrium dynamics of driven Fermi Condensates using three species

ORAL

Abstract

We study the non-equilibrium response of a strongly interacting, harmonically trapped Fermi gas following an effective quench of the interaction strength. The quench is realised by a complete population transfer of one of its constituting species to a third internal level via a radio-frequency pulse. The Fermi gas is modelled as a three-component Hubbard model, and we use the time-dependent matrix-product state method to gain insights into the condensate dynamics of the fully interacting fermionic gas in the low density limit. We observe non-trivial pairing dynamics influenced by the excitation of a collective mode of the trap and its interplay with the arising density inhomogeneity. These findings are compared to recent experimental results.
