Abstract

We present the results of an infinite order unitary transformation applied to a multiband Hubbard Hamiltonian by which it can be shown rigorously that an attractive interaction term appears at the oxygen ion sites as a result of oxygen-copper virtual charge excitations. This exact result yields convincing evidence that the pairing mechanism in two and/or three band Hubbard models results precisely from this attraction.
