Localized Collisions and the Black Hole Interior

This seminar will be presented in-person in Wolfensohn Hall at the IAS and on Zoom.

For contact-tracing purposes all off-campus attendees must register for this seminar: 

All in-person attendees must be fully vaccinated, INCLUDING A BOOSTER DOSE. Masks are optional in all indoor spaces. Additionally, all off-campus attendees are required to upload proof of vaccination via the IAS CrowdPass App 

Abstract: We study collisions of localized shockwaves behind the horizon of the eternal AdS black hole. We give a holographic boundary description in terms of the overlap of two growing perturbations in a shared quantum circuit. Due to a competition between different physical effects, the circuit analysis shows dependence on the transverse locations and exhibits four regimes of qualitatively different behaviors. On the gravity side we study properties of the post-collision geometry, using exact calculations in simple setups and estimations in more general circumstances. We show that the circuit analysis offers intuitive and surprisingly accurate predictions about gravity computations involving non-linear features of general relativity. Based on work with Ying Zhao [2202.04661].
