Boundary anomaly detection in two-dimensional subsystem symmetry-protected topological phases
Ke Ding, Hao-Ran Zhang, Bai-Ting Liu +1
We generalize the topological response theory to detect the boundary anomalies of linear subsystem symmetries. This approach allows us to distinguish different subsystem symmetry-p…
