Скачать или смотреть The Final Breath of a Black Hole: How Quantum Fluctuations Slow Down Hawking Radiation

This video explains the quantum-corrected evaporation process of rotating black holes, based on the publicly-available research paper. It focuses on what the data supports—such as the slowed energy decay rates and the existence of a quantum transparency window—and what it does not, specifically the reliability of semiclassical thermodynamics at extremely low temperatures.

This research contributes to the ongoing study of quantum gravity, Hawking radiation, and the thermodynamics of near-extremal black holes. It explores the evaporation history of Kerr-Newman spacetimes by applying a Schwarzian effective action to the near-horizon AdS2 throat region. The study examines quantum fluctuations and superradiance rather than purely semiclassical mechanisms to explain how energy decay is suppressed at late times. It utilizes concepts such as greybody factors, s−wave channels, and di-particle emission to track the evolution of angular momentum and mass as a black hole approaches its final state. By identifying a quantum absorption cross-section, the authors demonstrate that rotating black holes may become "transparent" to certain particles like photons and gravitons under specific conditions.
