Interplay between Zhang-Rice singlets and high-spin states in a model for doped NiO2 planes

Superconductivity found in doped NdNiO2 is puzzling as two local symmetries of doped NiO2 layers compete, with presumably far-reaching implications for the involved mechanism: A cupratelike regime with Zhang-Rice singlets is replaced by local triplet states at realistic values of charge-transfer ene...
