Information paradox and corrected thermodynamics for black holes

Publication date: 10 December 2019Source: Physics Letters B, Volume 799Author(s): Ming ZhangAbstractWe generally consider that entropy and temperature of a spherically symmetric black hole are corrected by quantum effect. We calculate interior entropy variation of massless scalar field and compare it with corrected Bekenstein-Hawking entropy variation for the evaporating black hole. We find that the corrected ratio between them is greater than the uncorrected one. The information paradox is then discussed.
