High Energy Theory Seminar

We present new results for Renyi entropy in CFT ground states. In particular, we describe advances in computation across non-spherical entangling surfaces and for generic Renyi index, applicable to arbitrary CFTs. These include the first rigorous computations of Renyi entropy across non-spherical entangling surfaces in strongly coupled 4d and 6d CFTs with holographic duals. A theme will be the central role of stress tensor correlators in determining CFT Renyi entropy.
