Title: Does Hawking Radiation Survive Beyond the Scrambling Time?
Date (JST): Thu, Jun 18, 2026, 13:30 - 15:00
Place: Seminar Room A
Abstract:
It is widely assumed that the standard Hawking radiation persists as long as a black hole remains much larger than the Planck length. In this talk, I will explore how UV physics can nevertheless dramatically modify the conventional properties of Hawking radiation, even in this semiclassical regime.
In particular, I will show that by incorporating nonlocal features inspired by string theory, Hawking radiation can become a transient phenomenon that is largely suppressed after the scrambling time, much earlier than the conventionally expected black hole lifetime. This suggests a major departure from the usual picture of black hole evaporation and may offer fresh insight into alternative resolutions of the information paradox.
