Calculation of the even-odd energy difference in superfluid Fermi systems using the pseudopotential theory
A. Csordás, G. Homa, P. Szépfalusy
The pseudopotential theory is extended to the Bogoliubov-de Gennes equations to determine the excess energy when one atom is added to the trapped superfluid Fermi system with even…

Gradient corrections to the local density approximation for trapped superfluid Fermi gases
András Csordás. Orsolya Almásy, Péter Szépfalusy
Two species superfluid Fermi gas is investigated on the BCS side up to the Feshbach resonance. Using the Greens's function technique gradient corrections are calculated to the gene…
