Pair-Breaking Collective Branch in BCS Superconductors and Superfluid Fermi Gases
Hadrien Kurkjian, S. N. Klimin, J. Tempere +1
We demonstrate the existence of a collective excitation branch in the pair-breaking continuum of superfluid Fermi gases and BCS superconductors. At zero temperature, we analyticall…
Transition from supersonic to subsonic waves in superfluid Fermi gases
Senne Van Loon, Wout Van Alphen, Jacques Tempere +1
We study the propagation of dispersive waves in superfluid Fermi gases in the BEC-BCS crossover. Unlike in other superfluid systems, where dispersive waves have already been studie…
Prethermalization to thermalization crossover in a dilute Bose gas following an interaction ramp
Mathias Van Regemortel, Hadrien Kurkjian, Iacopo Carusotto +1
The dynamics of a weakly interacting Bose gas at low temperatures is close to integrable due to the approximate quadratic nature of the many-body Hamiltonian. While the short-time…
