SELF-ENERGY CORRECTIONS IN TRANSITION-METAL OXIDES

We calculate the quasiparticle band structure of MnO, NiO and CaCuO2 u sing a model self-energy correction which closely approximates the GW method, Relative to LSD, our results substantially improve the agreeme nt with photoemission experiments, energy gaps and magnetic moments. O ur results demonstrate that the addition of self-energy corrections to LSD band calculations provide a meaningful description of many aspect s of the electronic states of transition metal oxides. Satellite struc tures found in photoemission experiments, however, are not found in ou r calculation.
