Orbital Physics Versus Spin Physics: the Orbital-Hubbard Model,in orbital space has important implications — superexchange contributes in all orbital ordered states, the Nagaoka theorem does not apply, and the kinetic energy is enhanced as compared with the spin case. As a result orbital-ordered states are destabilized by doping, and instead a strongly correlated . with disordered orbitals is realized.

The topic of electron correlation is a fundamental one in the field of condensed matter, and one that is being very actively studied both experimentally and theoretically at the present time. The manifestations of electron cor- relation are

A lower QP dispersion and quantum decoherence are obtained due to the inter-planar hole-magnon scattering in the .AF phase which disproves the classical concept of a ferromagnetic polaron.
