Solving the semiclassical problem with holography
Prof. Robie Hennigar
Durham University

Semiclassical gravity has the potential to address several interesting problems in foundational physics, such as the evaporation of black holes, but its defining equations are notoriously difficult to solve. In this talk, I will introduce braneworld holography which can solve the semiclassical problem exactly in certain three-dimensional settings. I will discuss how four-dimensional C-metrics allow one to obtain three-dimensional quantum black holes incorporating all orders of semiclassical backreaction. Time permitting, I will illustrate how this framework can be used to test ideas about cosmic censorship in semiclassical gravity.
