Flux-Fusion Anomaly Test and Bosonic Topological Crystalline Insulators
We introduce a method, dubbed the flux-fusion anomaly test, to detect certain anomalous symmetry fractionalization patterns in two-dimensional symmetry-enriched topological (SET) phases. We focus on bosonic systems with Z_{2} topological order and a symmetry group of the form G=U(1)⋊G^{′}, where G^{...
