A Page curve for an evaporating black hole in asymptotically flat spacetime is computed by adapting the Quantum Ryu-Takayanagi (QRT) proposal to an analytically solvable semi-classical two-dimensional dilaton gravity theory. The Page time is found to be one third of the black hole lifetime, at leading order in semi-classical corrections. A Page curve is also obtained for a semi-classical eternal black hole, where energy loss due to Hawking evaporation is balanced by an incoming energy flux.

    The paper proposes a weighted-sum revision of the quantum extremal surface formula, but the weight is assumed rather than derived.

    hep-th 2025-06 conditional novelty 6.0 of 10

    A Schwarzschild-like black hole in a dimensionally reduced dilaton gravity model evaporates completely, ending in Minkowski space-time with a thunderpop shockwave.

  4. Page Curve for an Evaporating Schwarzschild Black Hole in Dimensionally-Reduced Model of Dilaton Gravity

    hep-th 2025-07 conditional novelty 5.0 of 10

    In a dimensionally-reduced dilaton-gravity model, the island formula produces a Page curve for an evaporating Schwarzschild black hole, with the entropy vanishing at the endpoint.

  5. Island of acoustic black hole in Schwarzschild spacetime

    hep-th 2025-12 conditional novelty 4.0 of 10

    For a Schwarzschild-surrounded acoustic black hole, phonon entanglement entropy follows a Page curve in the non-extremal case but diverges (no Page time) in the extremal case, according to the island formula.
