In a 2d evaporating black hole model, large boosts create O(1/G_N) gradients in bulk entropy that move the quantum extremal surface, causing the generalized entropy to follow unitary expectations with information disappearing after a scrambling time and a phase transition at the Page time.

abstract
We address proposed alternatives to the black hole firewall. We show that embedding the interior Hilbert space of an old black hole into the Hilbert space of the early radiation is inconsistent, as is embedding the semi-classical interior of an AdS black hole into any dual CFT Hilbert space. We develop the use of large AdS black holes as a system to sharpen the firewall argument. We also reiterate arguments that unitary non-local theories can avoid firewalls only if the non-localities are suitably dramatic.

A quantum Maxwell demon near a black hole horizon loses some work extraction ability for external observers due to information inaccessibility but obeys local thermodynamics and preserves the equivalence principle for internal observers.

The entropy of bulk quantum fields and the entanglement wedge of an evaporating black hole
In a 2d evaporating black hole model, large boosts create O(1/G_N) gradients in bulk entropy that move the quantum extremal surface, causing the generalized entropy to follow unitary expectations with information disappearing after a scrambling time and a phase transition at the Page time.

Quantum Maxwell Demon at the Black Hole Horizon: Thermodynamics, Information, and the Equivalence Principle
A quantum Maxwell demon near a black hole horizon loses some work extraction ability for external observers due to information inaccessibility but obeys local thermodynamics and preserves the equivalence principle for internal observers.
