Doping-dependent character and possible magnetic ordering of NdNiO
Frank Lechermann
The novel nickelate superconductors of infinite-layer type feature challenging electronic pecularities in the normal-state phase diagram with doping. Distinct many-body behavior an…
From basic properties to the Mott design of correlated delafossites
Frank Lechermann
The natural-heterostructure concept realized in delafossites highlights these layered oxides. While metallic, band- or Mott-insulating character may be associated with individual l…
Spatial inhomogeneity and the metal-insulator transition in Ca(RuTi)O
Frank Lechermann, Qiang Han, Andrew J. Millis
Turning a pristine Mott insulator into a correlated metal by chemical doping is a common procedure in strongly correlated materials physics, e.g. underlying the phenomenology of hi…
Multiorbital processes rule the NdSrNiO normal state
Frank Lechermann
The predominant Ni-multiorbital nature of infinite-layer neodynium nickelate at stoichiometry and with doping is revealed. We investigate the correlated electronic structure of NdN…
