Abstract

We investigate the competition of various exotic superfluid states in a chain of spin-polarized ultracold fermionic atoms with hyperfine spin F = 3/2 and s-wave contact interactions. We show that the ground state is an exotic inhomogeneous mixture in which two distinct superfluid phases – spin-carrying pairs and singlet quartets – form alternating domains in an extended region of the parameter space.
