Abstract

Non-perturbative UV effects are believed to be essential for resolving the black hole information paradox. Yet, an equally important question is whether such effects could also largely alter Hawking radiation itself, the process that led to the paradox in the first place.

In this talk, I will explore this possibility and discuss how UV physics can dramatically modify the standard properties of Hawking radiation predicted by low-energy effective field theory.

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.
