SUMMARY:Lecture / Discussion:Brown Bag Seminar | Algebras\, ergodicity\, and the emergence of causality
DESCRIPTION:Given a general many-body quantum system\, how can we diagnose whether a holographic causal structure emerges as its number of degrees of freedom goes to infinity? In this talk\, I will explain which general tools the language of von Neumann algebras provides us with to address this question. In particular\, I will show that a sharp horizon structure emerges in the dual of N=4 SYM theory at finite 't Hooft coupling\, which allows to make sense of causality at nonzero string length in string theory. I will also elaborate on an intriguing interplay between the algebraic results we will encounter and the theory of chaos in classical and quantum dynamical systems.
