Wesystematically apply density functional theory to determine the kind ofinhomogeneities that spontaneously develop in a homogeneous gapless phase ofneutral two-flavor superfluid quark matter. We consider inhomogeneities in thequark and electron densities and in the phases and amplitudeof the order parameter. These inhomogeneities are expected to leadthe gapless phase to a BCS-normal coexisting phase, a Larkin-Ovchinnikov-Fulde-Ferrell(LOFF) state with phase oscillations alone, and a LOFF statewith amplitude oscillations. Using a simple model for the energydensity functional, we find that which of them the homogeneoussystem tends towards depends sensitively on the chemical potential separationbetween up and down quarks and the gradient energies.
