摘要
The notion of a quantum phase is a macroscopic one. In this talk, I will show that the macroscopic observables in two gapped quantum phases realized by the Ising chain form two enriched fusion categories. Generalizing to arbitrary finite onsite symmetries, we immediately recover the well-known classification of all 1-dimensional gapped quantum phases. This is a joint work with Xiao-Gang Wen and Hao Zheng.
