Molecular superfluid phase in one-dimensional multicomponent fermionic cold atoms
Abstract
We study a simple model of N-component fermions with contact interactions which describes fermionic atoms with N = 2F + 1 hyperfine states loaded into a one-dimensional optical lattice. We show by means of analytical and numerical approaches that, for attractive interaction, a quasi-long-range molecular superfluid phase emerges at low density. In such a phase, the pairing instability is strongly suppressed and the leading instability is formed from bound-states made of N fermions.
