Abstract
A canonical two-band BCS Hamiltonian containing a Fermi surface of d holes and p holes for the high- 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 droplets that undergoes a phase-locking transition at a critical temperature below the mean-field solution. Recent NMR and neutron-scattering results are discussed.
