Rotating the Replica: Twisted Rényi Coefficients from CFT Operator Counting

We show that twisting vacuum Rényi entropies by a spatial rotation reveals conformal field theory data governing the asymptotic counting of spinning operators. For a ball in four dimensions, the logarithmic coefficients of these angular-momentum-twisted Rényi entropies are determined by rotating-sphere thermal data to all orders in the local derivative expansion, including the Weyl-anomaly contribution. We test this relation in free theories and in strongly coupled, large-N N=4 Yang--Mills theory using holography.
