Recently, new holographic models of black hole evaporation have given fresh insights into the information paradox [1–3]. In these models, the black hole evaporates into an auxiliary bath space after a quantum quench, wherein the holographic theory and the bath are joined. One particularly exciting development is the appearance of ‘ER=EPR’-like wormholes in the (doubly) holographic model of [3]. At late times, the entanglement wedge of the bath includes the interior of the black hole. In this paper, we employ both numerical and analytic methods to study how information about the black hole interior is encoded in the Hawking radiation. In particular, we systematically excise intervals from the bath from the system and study the corresponding Page transition. Repeating this process ad infinitum, we end up with a fractal structure on which the black hole interior is encoded, implementing the überholography protocol of [4].

• Quantum extremal islands made easy. Part II. Black holes on the brane (2020, methodology): “ert action is topological and so it is common to instead consider Jackiw-Teitelboim (JT) gravity [111,112] in the brane theory (e.g., see recent discussions of quantum extremal islands in d= 2, e.g., [2,13,15,113]). Following [1], we then choose the brane action as I brane = I JT 1 4ˇG bulk L Z d2x ”
• Islands in Schwarzschild black holes (2020, result): “So far, among recent works [5–8, 12, 13, 17–27], the island rule has been studied mainly in two spacetime dimensions,1 which offer a tractable treatment of the entanglement entropy of the Hawking radiation.”
