SU(4)-symmetric spin-orbital liquids on the hyperhoneycomb lattice

Willian M. H. Natori, Eric C. Andrade, Rodrigo G. Pereira

We study the effective spin-orbital model that describes the magnetism of 4$d^1$ or 5$d^1$ Mott insulators in ideal tricoordinated lattices. In the limit of vanishing Hund's coupli…
