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…
