Fractionalization and Anomalies in Symmetry-Enriched U(1) Gauge Theories

We classify symmetry fractionalization and anomalies in a (3+1)d U(1) gauge theory enriched by a global symmetry group \(G\). We find that, in general, a symmetry-enrichment pattern is specified by 4 pieces of data: \(\rho\), a map from \(G\) to the duality symmetry group of this \(\mathrm{U}(1)\) g...
