Molecular superfluid phase in systems of one-dimensional multicomponent fermionic cold atoms
Molecular superfluid phase in systems of one-dimensional multicomponent fermionic cold atoms
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 …
