Local spin operators are used as artificial orbitals to construct an effective band structure for the Kitaev spin liquid, and symmetry indicators predict chiral edge modes.
Action of the symmetries on the unit cellR =n1a1 +n2a2↦→n′ 1a1 +n′ 2a2, sublattices (δA, δB)↦→(δ′ A, δ′ B) and spin operators (Sx,S y,S z)≡ (x,y,z )↦→(x′,y′,z′)
