| We present a model for cuprate superconductivity based on the identification of an experimentally detected local superconductor as a charge 2 fermion pairing in a circular, stationary density wave. This wave acts like a highly correlated local boson satisfying a modified Cooper problem with additional correlation stabilization relative to the separate right- and left-handed density waves composing it. This local boson could be formed in a two-bound roton-like manner; it has Fermion statistics. Delocalized superconductive pairing (superconductivity) is achieved by a Feshbach resonance of two unpaired holes (electrons) resonating with a virtual energy level of the bound pair state of the local boson as described by the previously discussed Boson-Fermion-Gossamer (BFG) model. The spin-charge order interaction offers a microscopic basis for the cuprate Tc's. The spin-charge interaction correlates Tc with experimental inelastic neutron and electron Raman scattering is proposed, based on the energy of the virtual bound pair. These and other modifications discussed, suggest a BFG-based microscopic explanation for the entire cuprate superconductivity dome shape. |
