Exact quantization of topological order parameter in SU( $N$ ) spin models, $N$ -ality transformation and ingappabilities

Hang Su, Yuan Yao, Akira Furusaki

We show that the ground-state expectation value of twisting operator is a topological order parameter for $U (1)$ - and $Z_{N}$ -symmetric symmetry-protected topologic…
