Title: Arithmetic Chaos Inside Black Holes

Abstract: It has been known for over 50 years that spacetime dynamics becomes chaotic in the approach to singularities. Furthermore, the classical gravitational dynamics exhibits remarkable number-theoretic properties known as arithmetic chaos. I will review these facts and give an explicit realisation of these phenomena in the interior of an asymptotically AdS black hole. I will discuss possible implications for the nature of black hole singularities and black hole thermodynamics.
Bio: Prof. Hartnoll completed his undergraduate and graduate studies at the University of Cambridge. He then did postdocs at the KITP in Santa Barbara and at Harvard, before joining the faculty at Stanford. After 10 years at Stanford he returned to Cambridge as the Professor of Mathematical Physics. He was awarded the New Horizons prize in 2015.
