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…
Polaronic effects of an impurity in a Fermi superfluid away from the BEC limit
Giovanni Lombardi, Jacques Tempere
In this article we study the interaction between an impurity and the gas of Bogoliubov excitations of a Fermi superfluid by mapping it on the polaron problem for an impurity in a B…
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…
Polarization of a quasi two-dimensional repulsive Fermi gas with Rashba spin-orbit coupling: a variational study
Alberto Ambrosetti, Giovanni Lombardi, Luca Salasnich +2
Motivated by the remarkable experimental control of synthetic gauge fields in ultracold atomic systems, we investigate the effect of an artificial Rashba spin-orbit coupling on the…
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…
