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 four pieces of data: ρ, a map from G to the duality symmetry group of this U(1) gauge theory which physica...
