In high-TC cuprates, superposition to a localized low-energy antiferromagnetic background of a delocalized high-energy assembly of exciton-solvated doping holes (ESH) accounts for singlet state hole pairing in real space, above TC. Below TC, pairs can glide in coherent motion along one-dimensional spines, formed by aligned charge transfer excitons, and serving as rails. Most of old and new experimental observations agree with this model. In high-TC cuprates, Coulomb interactions between exciton-solvated doping holes (ESH) can result in real-space pairing of holes.< Réduire
