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…

Sound velocity and dimensional crossover in a superfluid Fermi gas in an optical lattice
T. Koponen, J. -P. Martikainen, J. Kinnunen +1
We study the sound velocity in cubic and non-cubic three-dimensional optical lattices. We show how the van Hove singularity of the free Fermi gas is smoothened by interactions and…

Beyond linear response spectroscopy of ultracold Fermi gases
J. Kinnunen, P. Torma
We study RF-spectroscopy of ultracold Fermi gas by going beyond the linear response in the field-matter interaction. Higher order perturbation theory allows virtual processes and e…
