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…

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…

Disorder and non-Hermiticity in Kitaev spin liquids with a Majorana Fermi surface
Lukas Rødland, Carlos Ortega-Taberner, Megha Agarwal +1
We study the effect of disorder on Z quantum spin liquids with a Majorana Fermi line (respectively surface in three dimensions) and show that depending on the symmetries that a…
