We review recent developments in Jackiw–Teitelboim gravity. This is a simple solvable
model of quantum gravity in two dimensions (that arises eg from the s-wave sector of higher …

We construct an infinite family of microstates with geometric interiors for eternal black holes
in general relativity with a negative cosmological constant in any dimension. Wormholes in …

A bstract We introduce a framework for quantifying random matrix behavior of 2d CFTs and
AdS 3 quantum gravity. We present a 2d CFT trace formula, precisely analogous to the …

The double-scaled matrix integral has as its leading density of states the universal Cardy
density of primaries in a two-dimensional CFT, thus motivating the name Virasoro minimal …

A bstract We study black holes in two and three dimensions that have spacelike curvature
singularities behind horizons. The 2D solutions are obtained by dimensionally reducing …

A bstract We conjecture a formula for the spectral form factor of a double-scaled matrix
integral in the limit of large time, large density of states, and fixed temperature. The formula …

A bstract We continue the study of random matrix universality in two-dimensional conformal
field theories. This is facilitated by expanding the spectral form factor in a basis of modular …

A bstract As shown by Louko and Sorkin in 1995, topology change in Lorentzian signature
involves spacetimes with singular points, which they called crotches. We modify their …

A bstract We propose an explicit realization of flat space holography in two dimensions
where both sides of the duality are independently defined and the boundary theory is …

There are two types of quantum chaos: eigenbasis chaos and spectral chaos. The first type
controls the early-time physics, eg the thermal relaxation and the sensitivity of the system to …
