Frustrated transition-metal compounds in which spin-orbit coupling (SOC) and electron correlation work together have attracted much attention recently. In the case of $5d$ transition metals, where SOC is large, ${j}_{\text{eff}}=1/2$ bands near the Fermi level are thought to encompass the essential physics of the material, potentially leading to a concrete realization of exotic magnetic phases such as the Kitaev spin liquid. Here, we derive a spin model on a triangular lattice based on ${j}_…

PhD Thesis: Searching for an emergent SU(4) symmetry in real materials
The enhancement of the spin-space symmetry from the usual $\mathrm{SU}(2)$ to $\mathrm{SU}(N)$ with $N>2$ is promising for finding nontrivial quantum spin liquids, but the realization of

Emergent SU(4) Symmetry in α-ZrCl_{3} and Crystalline Spin-Orbital Liquids.
TLDR
A new mechanism by which SU(4) symmetry emerges in the strong spin-orbit coupling limit of α-ZrCl_{3}=3/2 quartets is proposed, and crystalline spin-orbital liquids protected by this emergent SU( 4) symmetry and space group symmetries are proposed.
