The Page curve exhibits a sharp peak at the Page time corresponding to a phase transition from an empty quantum extremal surface to a non-empty one. This study delves into the impact of this phase transition on the informational content of black hole radiation through constructing a smooth Page curve which represents a gradual transition instead. We utilize replica trick, apply holography in a specific form, and introduce mathematical identities inherent to the curve's smoothness. Our results suggest that a gradual transition could lead to a significant increase in the informational content of the radiation.

  1. Replica wormhole and AMPS firewall

    hep-th 2024-11 reject novelty 5.0 of 10

    The authors propose that the replica wormhole's Ricci scalar singularity produces a delta-function firewall force on infalling particles, resolving both the information paradox and the AMPS argument.

    hep-th 2025-01 conditional novelty 4.0 of 10

    In JT gravity toy models, late-time modular entropy and capacity of entanglement scale inversely with n times the inverse temperature, supporting a thermal reading of the replica parameter.
