Bose-Einstein condensation temperature of a gas of weakly dissociated diatomic molecules
L. M. Jensen, H. Mäkelä, C. J. Pethick
We consider the properties of a gas of bosonic diatomic molecules in the limit when few of the molecules are dissociated. Taking into account the effects of dissociation and scatte…
Fermion pairing with spin-density imbalance in an optical lattice
T. Koponen, J. Kinnunen, J. -P. Martikainen +2
We consider pairing in a two-component atomic Fermi gas, in a three-dimensional optical lattice, when the components have unequal densities, i.e. the gas is polarized. We show that…
BCS-BEC Crossover in Atomic Fermi Gases with a Narrow Resonance
L. M. Jensen, H. M. Nilsen, Gentaro Watanabe
We determine the effects on the BCS-BEC crossover of the energy dependence of the effective two-body interaction, which at low energies is determined by the effective range. To des…
Non-BCS superfluidity in trapped ultracold Fermi gases
L. M. Jensen, J. Kinnunen, P. Torma
Superconductivity and superfluidity of fermions require, within the BCS theory, matching of the Fermi energies of the two interacting Fermion species. Difference in the number dens…
Strongly interacting Fermi gases with density imbalance
J. Kinnunen, L. M. Jensen, P. Torma
We consider density-imbalanced Fermi gases of atoms in the strongly interacting, i.e. unitarity, regime. The Bogoliubov-deGennes equations for a trapped superfluid are solved. They…
Non-universal BCS-BEC crossover in resonantly interacting Fermi gases
L. M. Jensen
We investigate the non-universal behavior of the BCS-BEC crossover model at the normal to superfluid transition. By using a finite temperature quantum field theoretical approach du…
