Query: Stability of FFLO states in optical lattices with bilayer structure   We investigate the stability of the superfluid state in a bilayer fermionic
optical lattice system with a confining potential, using the Bogoliubov
de-Gennes equations. It is clarified that in the imbalanced case, the
introduction of the interlayer hopping stabilizes the radial
Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state, while makes the angular FFLO
state unstable. We also discuss the system size dependence of the superfluid
ground state. It is clarified that in a certain ring region the A-FFLO state is
indeed realized in a large system.
