Three-dimensional spin-orbital liquids
Anna Sandberg, Lukas Rødland, Maria Hermanns
Spin-orbital liquids provide an exactly solvable route to three-dimensional Z2 quantum spin liquids beyond the original Kitaev setting. Built from higher-dimensional Clifford-algeb…

Between Mott and cluster Mott: spin-orbit entangled dimer singlets in BaCeRuO
L. Pätzold, A. Sandberg, H. Schilling +8
The hexagonal 4d ruthenates Ba3MRu2O9 host structural dimers and exhibit a delicate balance of competing interactions. Hund's coupling, trigonal crystal-field splitting, and hoppin…

Quasimolecular electronic structure of the trimer iridate BaNbIrO
M. Magnaterra, A. Sandberg, H. Schilling +17
The insulating mixed-valent Ir compound BaNbIrO hosts two holes per IrO trimer unit. We address the electronic structure via resonant inelastic…
