Dependence of the 1S0 superfluid pairing gap on nuclear interactions

Nucleon-nucleon (NN) interactions are well constrained for relative momenta k 2 fm−1 by existing scattering data [1]. The model dependences for larger momenta can be seen, for instance, in the P2 superfluid pairing gaps for Fermi momenta kF > 2 fm−1 [2]. In Ref. [3], we study in detail the dependence of the S0 superfluid gap on nuclear interactions at the BCS level, and on the resolution scale....

Pairing and superfluid properties of dilute fermion gases at unitarity

We study the system of a dilute gas of fermions in three dimensions, with attractive interactions tuned to the unitarity point, using the nonperturbative restricted path-integral Monte Carlo method. The pairing and superfluid properties of this system are calculated at finite temperature. The total energy at very low temperature from our results agrees closely with that of previous ground-state...

On the Superconductivity in the Induced Pairing Model

The two component model of coexisting local electron pairs and itinerant fermions coupled via charge exchange mechanism, which mutually induces superconductivity in both subsystems, is discussed. The cases of isotropic s-wave and anisotropic pairing of extended s and dx2−y2 -wave symmetries are analyzed for a 2D square lattice within the BCS-mean field approximation and the Kosterlitz-Thouless ...

Characteristics of two-dimensional quantum turbulence in a compressible superfluid.

Fluids subjected to suitable forcing will exhibit turbulence, with characteristics strongly affected by the fluid's physical properties and dimensionality. In this work, we explore two-dimensional (2D) quantum turbulence in an oblate Bose-Einstein condensate confined to an annular trapping potential. Experimentally, we find conditions for which small-scale stirring of the condensate generates d...
