Manifest charge-transfer physics in T $^{'}$ -La $_{2}$ NiO $_{4}$

Wiktoria Lewandowski, Steffen BÃ¶tzel, Ilya M. Eremin +1

The La $_{2}$ NiO $_{4}$ compound stabilizes in nature in the so-called T structure with octahedral oxygen coordination of the Ni site. Motivated by a similarly existing polymorph for La$…

Density waves in low-pressure bilayer nickelates

Lauro B. Braz, Steffen Bötzel, Steffen BÃ¶tzel +5

The low-pressure phase diagram of La $_{3}$ Ni $_{2}$ O $_{7}$ provides an important reference for understanding its pressure-induced high-temperature superconductivity. While the spin-densit…

Electronic instability, layer selectivity and Fermi arcs in La $_{3}$ Ni $_{2}$ O $_{7}$

Frank Lechermann, Steffen BÃ¶tzel, Ilya M. Eremin

Using advanced dynamical mean-field theory on a realistic level we study the normal-state correlated electronic structure of the high-pressure superconductor La $_{3}$ Ni $_{2}$ O $_{7}$ and…
