With so much data, it is often hard to match objects to one another across surveys. That's why one group at Johns Hopkins University turned to data science to develop a new method of making such matches.

*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.
