We show that Larkin-Ovchinnikov (LO) states with modulated superfluid order parameters have a considerably larger range of stability in a lattice than in the continuum. We obtain the phase diagram for the 3D cubic attractive Hubbard model with an unequal population of up and down fermions using the Bogoliubov-de Gennes fully self-consistent method. We find a strong modulation of the local polarization that should provide a distinct signature for detection of the LO phase. The shell structure in… Expand

Phase separations induced by a trapping potential in one-dimensional fermionic systems as a source of core-shell structures
TLDR
This work shows a possible occurrence of the core-shell structure in a system with a harmonic trap, containing the BCS and FFLO states and investigates the properties of such structures within an attractive Fermi gas loaded in the optical lattice, in the presence of the trapping potential and their relations to the phase diagram of the homogeneous system.
