Title: Applications of black hole scattering
Abstract:
In this talk, I will describe scattering in the presence of black holes. I will try to convince you that i) there is a new regime in the phase space of quantum gravity where scattering amplitudes can reliably be calculated in the low energy theory, ii) Hawking's free field theory breaks down after Page time (implying information retrieval in local effective field theory), and that iii) there is an emergent soft limit near the horizon, resulting in new soft graviton theorems in the presence of black holes. Finally, I will conclude with some more applications.
