Low-energy perspective of interacting electrons in the normal state of superconducting bilayer nickelate
Frank Lechermann, Steffen Bötzel, Ilya M. Eremin
Developing a low-energy model is essential for understanding unconventional superconductivity in bilayer nickelate LaNiO. Here, we analyze distinct low-energy scenarios…

Interplay of orbital-selective Mott criticality and flat-band physics in LaNiO
Frank Lechermann, Steffen Bötzel, Ilya M. Eremin
Superconductivity in nickelates apparently takes place in two different Ni oxidation regimes, namely either for infinite-layer-type compounds close to Ni, or for Ruddlesden-P…
