In pure AdS3 gravity, I will present a rigorous bound on boundary reflected entropy in terms of a topological feature of bulk spacetime (the “edge count”), and give an interpretation of the bound in terms of irreducible multipartite entanglement structures in holography. I … Read More

Streaming link https://berkeley.zoom.us/j/370438207 Abstract: The late-time, long-distance behaviour of gravitational perturbations of planar AdS black holes is controlled by hydrodynamic quasinormal modes. In the dual CFT these are modes of the conserved currents which control the infra-red dynamics. While the on-shell structure of these modes has been understood for a long-time, we have recently begun to understand how to construct an off-shell … Read More
