Collective excitations of a charged Fermi superfluid in the BCS-BEC crossover
S. N. Klimin, J. Tempere, T. Repplinger +1
We consider collective excitations in the superfluid state of Fermi condensed charged gases. The dispersion and damping of collective excitations at nonzero temperatures are examin…
Linear response of a superfluid Fermi gas inside its pair-breaking continuum
H. Kurkjian, J. Tempere, S. N. Klimin
We study the signatures of the collective modes of a superfluid Fermi gas in its linear response functions for the order-parameter and density fluctuations in the Random Phase Appr…
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…
Diversified vortex phase diagram for a rotating trapped two-band Fermi gas in the BCS-BEC crossover
S. N. Klimin, J. Tempere, M. V. Milošević
We report the equilibrium vortex phase diagram of a rotating two-band Fermi gas confined to a cylindrically symmetric parabolic trapping potential, using the recently developed fin…
Finite temperature vortices in a rotating Fermi gas
S. N. Klimin, J. Tempere, N. Verhelst +1
Vortices and vortex arrays have been used as a hallmark of superfluidity in rotated, ultracold Fermi gases. These superfluids can be described in terms of an effective field theory…
Finite temperature effective field theory and two-band superfluidity in Fermi gases
S. N. Klimin, J. Tempere, G. Lombardi +1
We develop a description of fermionic superfluids in terms of an effective field theory for the pairing order parameter. Our effective field theory improves on the existing Ginzbur…
