Abstract:The Renyi entropy is a generalization of entanglement entropy which can be used to further characterize the ground state of a quantum field theory. I'll present an observable, analogous to the Renyi entropy, which is defined for a 3d gauge theory preserving four supercharges, and which preserves a subset of the supersymmetry. Using localization techniques, this supersymmetric Renyi entropy can be calculated exactly for a variety of strongly coupled 3d gauge theories.
