Low-energy description of the metal-insulator transition in the rare-earth nickelates
Alaska Subedi, Oleg E. Peil, Antoine Georges
We propose a simple theoretical description of the metal-insulator transition of rare-earth nickelates. The theory involves only two orbitals per nickel site, corresponding to the…

Orbital Polarization in Strained LaNiO: Structural Distortions and Correlation Effects
Oleg E. Peil, Michel Ferrero, Antoine Georges
Transition-metal heterostructures offer the fascinating possibility of controlling orbital degrees of freedom via strain. Here, we investigate theoretically the degree of orbital p…
