Finiteness of entanglement entropy in a quantum black hole

Abstract: A logarithmic but divergent term usually appears in the computation of entanglement entropy circumferencing a black hole, while the leading quantum correction to the Bekenstein-Hawking entropy also takes the logarithmic form. A quench model of CFT within finite Euclidean time was proposed in the [1] to regard this logarithmic term as entanglement between radiation and the black hole, and this proposal was justified by the alternative sign for n-partite quantum information. However, this preliminary form suffer… Show more

“…This conjecture obviously reminds one of the Bekenstein-Hawking entropy formula and the two things indeed seem related in various ways. [11][12][13][14] It needs to be emphasized that the Ryu-Takyanagi conjecture uses only a tiny amount of the full power of Maldacena's duality. In particular in scenarios of AdS 3 /CF T 2 where it has been extensively checked one needs to take the limit of large central charge on the CFT side and by virtue of the Brown-Henneux formula we understand that to be a "semiclassical" limit.…”
