Hartree shift and pairing gap in ultracold Fermi gases in the framework of low-momentum interactions
Michael Urban, S. Ramanan
In this paper we consider a two-component gas of fermions on the BCS side of the BCS-BEC crossover at zero temperature. We use a momentum dependent interaction that reproduces the…
Pairing correlations of cold fermionic gases at overflow from a narrow to a wide harmonic trap
A. Pastore, P. Schuck, M. Urban +2
Within the context of Hartree-Fock-Bogoliubov theory, we study the behavior of superfluid Fermi systems when they pass from a small to a large container. Such systems can be now re…
Bose-Fermi Pairs in a Mixture and the Luttinger Theorem within a Nozieres-Schmitt-Rink like Approach
T. Sogo, P. Schuck, M. Urban
Bose-Fermion pair correlations in a mixture are considered at zero temperature in the T-matrix approximation. Special attention is paid to the Luttinger theorem. In a strict RPA va…
Spontaneous generation of spin-orbit coupling in magnetic dipolar Fermi gases
T. Sogo, M. Urban, P. Schuck +1
The stability of an unpolarized two-component dipolar Fermi gas is studied within mean-field theory. Besides the known instability towards spontaneous magnetization with Fermi sphe…
