Manifest charge-transfer physics in T-LaNiO
Wiktoria Lewandowski, Steffen Bötzel, Ilya M. Eremin +1
The LaNiO 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$…
Electronic theory for scanning tunneling microscopy spectra in bilayer nickelate thin films
Marius Scholten, Steffen Bötzel, Frank Lechermann +2
Recent Scanning Tunneling Microscopy (STM) experiments measuring the superconducting gap features in thin films of superconducting bilayer nickelates La2PrNi2O7 at ambient pressure…
Density waves in low-pressure bilayer nickelates
Lauro B. Braz, Steffen Bötzel, Steffen Bötzel +5
The low-pressure phase diagram of LaNiO provides an important reference for understanding its pressure-induced high-temperature superconductivity. While the spin-densit…
Structural symmetry effects on the competition of density waves and superconductivity in bilayer nickelates
Steffen Bötzel, Aiman Al-Eryani, Jun Zhan +4
We investigate the interplay between spin-density-wave (SDW) order and superconductivity in the bilayer nickelate LaNiO using the functional renormalization group~(fRG)…
Influence of ligand field and correlation on the electronic structure of NiO and CoO from DFT+DMFT calculations
Daniel Mutter, Frank Lechermann, Daniel F. Urban +1
The intriguing physics and rich application potential of strongly correlated first-row transition metal oxide compounds result from the complex interplay of several factors that in…
Co-operating multiorbital and nonlocal correlations in bilayer nickelate
Evgeny A. Stepanov, Steffen Bötzel, Ilya M. Eremin +1
The interplay of multiorbital physics and nonlocal self-energy effects is studied within an effective three-orbital model for the high-pressure normal state of superconducting bila…
