Abstract

We compute the central charge C-T and universal conductivity C-J of N-F fermions coupled to a U(1) gauge field up to next-to-leading order in the 1/N-F expansion. We discuss implications of these precision computations as a diagnostic for response and entanglement properties of interacting conformal field theories for strongly correlated condensed matter phases and conformal quantum electrodynamics in 2 + 1 dimensions.
