Photon rings around black holes saturate the quantum chaos bound via Lyapunov exponents of null geodesics and OTOCs in the near-ring region.
Identification of a new infinite-dimensional asymptotic symmetry algebra with central extensions for the four-dimensional Nappi-Witten spacetime, whose phase space includes general pp-wave metrics and Penrose limits of Kerr black holes.
