Super-shell structures and pairing in ultracold trapped Fermi gases
M. Ogren, H. Heiselberg
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 potenti…
Collective modes of trapped gases at the BEC-BCS crossover
H. Heiselberg
The collective mode frequencies in isotropic and deformed traps are calculated for general polytropic equation of states, , and expressed in terms of and the…
Cooper pairing and single particle properties of trapped Fermi gases
G. M. Bruun, H. Heiselberg
We calculate the elementary excitations and pairing of a trapped atomic Fermi gas in the superfluid phase. The level spectra and pairing gaps undergo several transitions as the str…
The few-body problem for trapped bosons with large scattering length
S. Jonsell, H. Heiselberg, C. J. Pethick
We calculate energy levels of two and three bosons trapped in a harmonic oscillator potential with oscillator length . The atoms are assumed to interact through a…
Cold Bose gases with large scattering lengths
S. Cowell, H. Heiselberg, I. E. Mazets +3
We calculate the energy and condensate fraction for a dense system of bosons interacting through an attractive short range interaction with positive s-wave scattering length . A…
Influence of Induced Interactions on the Superfluid Transition in Dilute Fermi Gases
H. Heiselberg, C. J. Pethick, H. Smith +1
We calculate the effects of induced interactions on the transition temperature to the BCS state in dilute Fermi gases. For a pure Fermi system with 2 species having equal densities…
