Entanglement in higher spin theories

There has been phenomenal recent progress in computing CFT entanglement and Renyi entropies, holographically and otherwise. We extend these investigations to the higher spin regime -- where sensible notions of geometry are sorely lacking -- by computing ground state Renyi entropies in certain classes of holographic CFTs with higher spin symmetry. Our calculations are performed at both classical and one-loop level, from gravity and CFT. Along the way, we establish some new general results about Renyi entropy in any CFT, higher spin symmetry aside.
