*Quantum chaos in two-dimensional gravity*

Two-dimensional gravity defines a toy paradigm in which the physics of 
gravitational systems is reduced to a bare minimum (essentially topology 
and symmetry). Its simplicity makes it an ideal testbed for holographic 
principles, a concrete realization of which was proposed by Kitaev in 
terms of his now famous SYK model. The SYK model is approximately dual 
to a two-dimensional bulk known as Jackiw-Teitelboim (JT) gravity. 
Intriguingly, we have come to understand that a third player (next to 
symmetry and topology) essential to the construction of that holographic 
correspondence is quantum chaos. In this seminar, I will try to review 
these developments. Starting from a quick review of the SYK model and JT 
gravity, we will discuss two conceptually independent bridges between 
these systems. In particular, we will discuss how concepts developed in 
the era of mesoscopics in the 90s in condensed matter physics are now 
becoming key in gravity. If time permits, we will also discuss how the 
Efetov supersymmetric sigma model (derived as a student at the Landau 
institute) now appears as a natural generalization of the above duality 
to string theory.
