Supersymmetric Rényi entropy and charged hyperbolic black holes

I will present an AdS/CFT computation matching the entropy of supersymmetric electrically charged hyperbolic black holes in four and six dimensions. Hyperbolic black holes are a class of black holes with non-compact horizons which are especially simple to deal with. The CFT calculation is a localization calculation on the squashed/branched sphere with vortex-like defect insertions. It is related in an interesting way to the Supersymmetric Rényi entropy of the dual gauge theory.
