Weconsider density-imbalanced Fermi gases of atoms in the strongly interacting,i.e., unitarity, regime. The Bogoliubov–de Gennes equations for a trapped superfluidare solved. They take into account the finite size ofthe system, as well as give rise to both phaseseparation and Fulde-Ferrel-Larkin-Ovchinnikov-type oscillations in the order parameter. We showhow radio-frequency spectroscopy reflects the phase separation, and can providedirect evidence of the FFLO-type oscillations via observing the nodesof the order parameter.
