Quantum Gravitational Corrections to Particle Creation by Black Holes and the Information Paradox

by Xavier Calmet (University of Sussex)

Wednesday 19 Jul 2023, 16:00 → 17:00 Asia/Seoul

Seminar Room (CTPU)

In this talk I present our solution to the information paradox published in Phys.Rev.Lett. 128 (2022) 11, 111301 and Phys.Lett.B 827 (2022) 136995  (see  EPL 139 (2022) 4, 49001 for a review). I show why Mathur theorem does not apply when quantum gravitational effects and macroscopic superposition are taken into account. I show that this leads to a unitary evolution of the black hole evaporation. Finally, I present our recent calculation of quantum gravitational corrections to Hawking amplitude (https://doi.org/10.1016/j.physletb.2023.137820) which leads to a non-thermal emission spectrum.
