Multi-orbital physics in inverse Lieb lattice altermagnets

Mercè Roig, Jannik Gondolf, Andreas Kreisel +2

The inverse Lieb lattice has recently emerged as a promising platform for altermagnetism, with several materials with this structure proposed as $d$ -wave altermagnetic candidates.…

Inherent momentum-dependent gap structure of altermagnetic superconductors

Christian L. H. Rasmussen, Jannik Gondolf, Mats Barkman +4

Altermagnetic metals break time-reversal symmetry and feature spin-split Fermi surfaces generated by compensated Néel-ordered collinear magnetic moments. Being metallic, such alter…

Local signatures of altermagnetism

Jannik Gondolf, Andreas Kreisel, Mercè Roig +3

Altermagnets constitute a class of collinear compensated Néel ordered magnets that break time-reversal symmetry and feature spin-split band structures. Based on versatile microscop…

Theory of magnetic excitations in multilayer nickelate superconductor La $_{3}$ Ni $_{2}$ O $_{7}$

Steffen Bötzel, Frank Lechermann, Jannik Gondolf +1

Motivated by the recent reports of high- $T_{c}$ superconductivity in La $_{3}$ Ni $_{2}$ O $_{7}$ under pressure, we analyzed theoretically the magnetic excitations in the normal and the superc…

Revisiting the metal-to-metal transition in $2 H$ -AgNiO $_{2}$

Jannik Gondolf, Ilya Eremin, Frank Lechermann

The layered delafossite compound AgNiO $_{2}$ with $2 H$ stacking symmetry undergoes a structural metal-to-metal transition at $T_{S} \sim 365$ K. It has been described in the past…

Electronic correlations and superconducting instability in La $_{3}$ Ni $_{2}$ O $_{7}$ under high pressure

Frank Lechermann, Jannik Gondolf, Steffen Bötzel +1

Motivated by the report of superconductivity in bilayer La $_{3}$ Ni $_{2}$ O $_{7}$ at high pressure, we examine the interacting electrons in this system. First-principles many-body theory i…
