Title: What Can Quantum Field Theory Teach Us About Black Holes (And Vice Versa)?

Abstract: The existence of black holes is a remarkable prediction of Einstein's General Theory of Relativity. The prediction was spectacularly confirmed by the detection at LIGO in 2015 of the gravitational waves emitted by a black hole merger. Despite this, the status of black holes in a more complete description of our universe including quantum mechanics has long remained mysterious, presenting puzzles for theorists which still remain unsolved.

The AdS/CFT Correspondence provides a striking and unexpected relation or "duality" between gravity and the quantum field theories which underly our understanding of particle physics.  AdS/CFT has provided new tools for studying the physics of black holes and has also led to progress in understanding the behaviour of QFT at strong coupling. In my talk, I will review the correspondence and some of the insights it has provided. I will also discuss the future prospects for resolving some of the hardest outstanding questions.

Profile: Nick Dorey received his PhD from Edinburgh University in 1991 and then held postdoctoral and junior faculty positions at Los Alamos National Laboratory, University of Washington and Swansea University.
