Critical islands

We discuss a doubly-holographic prescription for black holes in braneworlds with vanishing cosmological constant. It involves calculating Ryu-Takayanagi surfaces AdS funnel spacetimes attached to braneworld the $ critical$ Randall-Sundrum II model. Critical have virtue of having massless gravitons. Our approach should be useful when is hole interacting deconfined, large-$N$ matter. In higher dimensions, explicit metrics will constructed numerically -- but based on general structure geometry, we present natural guess where one might find semi-classical island. 3-dimensional example toy analytic known, can check our by direct calculation. argue that this resolves version information paradox these systems, finding strong evidence "cosmological islands". Comoving and associated UV cut-offs brane, play roles.
