Collective excitations of superfluid Fermi gases near the transition temperature
S. N. Klimin, J. Tempere, H. Kurkjian
Studying the collective pairing phenomena in a two-component Fermi gas, we predict the appearance near the transition temperature of a well-resolved collective mode of quadra…
Dark soliton collisions in superfluid Fermi gases
Wout Van Alphen, Giovanni Lombardi, Sergei N. Klimin +1
In this work dark soliton collisions in a one-dimensional superfluid Fermi gas are studied across the BEC-BCS crossover by means of a recently developed finite-temperature effectiv…
Snake instability of dark solitons across the BEC-BCS crossover: an effective field theory perspective
Giovanni Lombardi, Wout Van Alphen, Sergei N. Klimin +1
In the present article the snake instability mechanism for dark solitons in superfluid Fermi gases is studied in the context of a recently developed effective field theory [Eur. Ph…
Verification of an analytic fit for the vortex core profile in superfluid Fermi gases
Nick Verhelst, Sergei Klimin, Jacques Tempere
A characteristic property of superfluidity and -conductivity is the presence of quantized vortices in rotating systems. To study the BEC-BCS crossover the two most common methods a…
Soliton core filling in superfluid Fermi gases with spin-imbalance
G. Lombardi, W. Van Alphen, S. N. Klimin +1
In this paper the properties of dark solitons in superfluid Fermi gases with spin-imbalance are studied by means of a recently developed effective field theory [S. N. Klimin, J. Te…
Phase correlations and quasicondensate in a two-dimensional ultracold Fermi gas
J. Tempere, S. N. Klimin
The interplay between dimensionality, coherence and interaction in superfluid Fermi gases is analyzed by the phase correlation function of the field of fermionic pairs. We calculat…
