Symmetries and anomalies of Kitaev spin-$S$ models: Identifying symmetry-enforced exotic quantum matter

Ruizhi Liu, Ho Tat Lam, Han Ma +1

We analyze the internal symmetries and their anomalies in the Kitaev spin-$S$ models. Importantly, these models have a lattice version of a ${\mathbb{Z}}_2$ 1-form symmetry, denoted…
