Black Hole Information Paradox and Wormholes

アブストラクト：
In recent research developments in the black hole information
paradox, it was found that the quantum extremal islands reproduce the
unitary Page curve of an evaporating black hole. The quantum extremal
island is derived by including replica wormholes in the gravitational path
integral, but for the transient, evaporating black holes most relevant to
Hawking's paradox, these wormholes have not been analyzed in any detail. In
this talk we study replica wormholes for black holes formed by
gravitational collapse in two-dimensional Jackiw-Teitelboim gravity, and
confirm that they lead to the island rule for the entropy of the Hawking
radiation.
