Disentangling lattice and electronic contributions to the metal-insulator transition from bulk vs. layer confined RNiO
Alexandru B. Georgescu, Oleg E. Peil, Ankit Disa +2
In complex oxide materials, changes in electronic properties are often associated with changes in crystal structure, raising the question of the relative roles of the electronic an…
Mechanism and Control Parameters of the Coupled Structural and Metal-Insulator Transition in Nickelates
Oleg E. Peil, Alexander Hampel, Claude Ederer +1
Rare-earth nickelates exhibit a remarkable metal-insulator transition accompanied by a structural transition associated with a lattice `breathing' mode. Using model considerations…
Charge self-consistent many-body corrections using optimized projected localized orbitals
Malte Schüler, Oleg E. Peil, Gernot J. Kraberger +5
In order for methods combining ab initio density-functional theory and many-body techniques to become routinely used, a flexible, fast, and easy-to-use implementation is crucial. W…
