Superfluid ground state of Fermi-Bose mixtures




We consider a mixture of fermionic (in two hyperfine states) and bosonic atoms at zero temperature. The only interactions taken into account are the contact interactions between fermions and bosons (described by the coupling constant gBF) and among the bosons themselves (described by gB). We neglect the interaction between distinguishable fermions on purpose and ask the question whether the strong enough attraction between bosons and fermions can induce pairing in fermionic component.
