Supershell structures and pairing in ultracold trapped Fermi gases
(2007) In Physical Review A (Atomic, Molecular and Optical Physics) 76(2).- Abstract
- We calculate level densities and pairing gaps for an ultracold dilute gas of fermionic atoms in harmonic traps under the influence of mean field and anharmonic quartic trap potentials. Supershell nodes, which were found in Hartree-Fock calculations, are calculated analytically within periodic orbit theory as well as from WKB calculations. For attractive interactions, the underlying level densities are crucial for pairing and supershell structures in gaps are predicted.
