Charge disproportionation without charge transfer in the rare-earth nickelates as a possible mechanism for the metal-insulator transition

Steve Johnston, Anamitra Mukherjee, Ilya Elfimov +2

We study a model for the metal-insulator (MI) transition in the rare-earth nickelates RNiO, based upon a negative charge transfer energy and coupling to a rock-salt like lattic…

A variational approach for calculating Auger electron spectra: going beyond the impurity approximation

Anamitra Mukherjee, George A. Sawatzky, Mona Berciu

We propose a novel variational method to calculate the two-hole propagators relevant for Auger spectroscopy in transition metal oxides. This method can be thought of as an intermed…
