Quantum Chaos and Regularity in Ultracold Fermi Gases
M. Puig von Friesen, M. Ogren, S. Aberg
Quantum fluctuation of the energy is studied for an ultracold gas of interacting fermions trapped in a three-dimensional potential. Periodic-orbit theory is explored, and energy fl…
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…
On the spin asymmetry of ground states in trapped two-component Fermi gases with repulsive interactions
M. Ogren, K. Karkkainen, Y. Yu +1
We examine the spin asymmetry of ground states for two-dimensional, harmonically trapped two-component gases of fermionic atoms at zero temperature with weakly repulsive short rang…
Super-shell structure in harmonically trapped fermionic gases and its semi-classical interpretation
M. Ogren, Y. Yu, S. Aberg +2
It was recently shown in self-consistent Hartree-Fock calculations that a harmonically trapped dilute gas of fermionic atoms with a repulsive two-body interaction exhibits a pronou…
