Superconductive solutions for a two-band Hamiltonian

A canonical two-band BCS Hamiltonian containing a Fermi surface of [ital d] holes and [ital p] holes for the high-[ital T][sub [ital c]] cuprate oxides is examined and is shown to possess two superconducting gaps. It is also pointed out that the system admits a precursor phase of Cooper-pair droplet...
