Title: Black Holes, Causality, and Critical Phenomena
Host: Liam McAllister
Abstract: Black holes, aside from their importance in astrophysics, play a crucial role in understanding quantum gravity and quantum field theory. I will describe how black holes provide a window into fundamental physics, focusing on our efforts to understand the mechanism for causality in quantum gravity. We will scatter from a black hole, then use the results to derive new constraints on quantum fields, and to make new predictions for ordinary matter including ferromagnets and boiling water near the critical point.
