Abstract
We show that thed-p model of ‘HighT c’ superconductivity can be mapped ontoa spin half Anderson latticewith vanishing conduction electron band width. Using the non-orthogonal basis of Zhang and Rice [1], we show that the orthogonalised combinations are very short range and make up a ‘conduction band’ for the resulting Anderson Lattice. The only motion is restricted to that with achange of orbital character.
