Superfluidity in system with fermion condensate
The properties of Fermi systems beyond the phase transition point, at which the group velocity of the quasiparticles changes sign on the Fermi surface, are analyzed. A Fermi condensate arises in the new phase: The energies e(p) of quasiparticles with momenta/7lc <p<p2c (Pic <Pf>Pic >Pf) turn out to be identical and equal to the chemical potential μ. If a Cooper pairing can occur in this phase, the gap Δ is a linear function of the pairing constant λ.
