Nodal Orbital-Anti-Phase Superconducting State in Bilayer Nickelates

Marius Scholten, Steffen Bötzel, Frank Lechermann +2

The recent discovery of high- superconductivity in the bilayer nickelate LaNiO (La-327) under applied pressure and compressive strain opened a new avenue to elucid…

Correlation-assisted spin-selective metallicity in strained and bilayer altermagnets

Marnin J. Di Nunzio, Frank Lechermann, Ilya M. Eremin

Altermagnets combine vanishing net magnetization with a momentum-dependent spin-split electronic structure, providing a route to spin-polarized carriers without ferromagnetism. Her…

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…

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)…

Density waves in low-pressure bilayer nickelates

Lauro B. Braz, Steffen Bötzel, Frank Lechermann +4

The low-pressure phase diagram of LaNiO provides an important reference for understanding its pressure-induced high-temperature superconductivity. While the spin-densit…
