Black Hole Interior and Quantum Error Correction with Dynamical Gravity
Akihiro Miyata, Tomonori Ugajin
According to the island formula, information in the code subspace defined in the black hole interior is embedded in the Hawking radiation after the Page time. At first sight, this…
The Petz (lite) recovery map for scrambling channel
Yasuaki Nakayama, Akihiro Miyata, Tomonori Ugajin
We study properties of the Petz recovery map in chaotic systems, such as the Hayden-Preskill setup for evaporating black holes and the SYK model. Since these systems exhibit the ph…
Mixed boundary conditions and Double-trace like deformations in Celestial holography and Wedge-like holography
Machiko Fukada, Akihiro Miyata
According to the AdS/CFT dictionary, adding a relevant double-trace deformation to a holographic CFT action is dual to imposing mixed Neumann/Dirichlet boundary conditi…
Entanglement between two evaporating black holes
Akihiro Miyata, Tomonori Ugajin
We study a thermo-field double type entangle state on two disjoint gravitating universes, say A and B, with an eternal black hole on each. As was shown previously, its entanglement…
A comment on a fine-grained description of evaporating black holes with baby universes
Norihiro Iizuka, Akihiro Miyata, Tomonori Ugajin
We study a partially fine-grained description of an evaporating black hole by introducing an open baby universe with a boundary. Since the Page's calculation of the entropy of Hawk…
Evaporation of black holes in flat space entangled with an auxiliary universe
Akihiro Miyata, Tomonori Ugajin
We study a thermofield double type entangled state on two disjoint universes and , where one of the universes is asymptotically flat containing a black hole. As we increase…
