This is a review of the Sachdev-Ye-Kitaev (SYK) model of compressible quantum many-
body systems without quasiparticle excitations, and its connections to various theoretical …

A bstract A two-dimensional CFT dual to a semiclassical theory of gravity in three
dimensions must have a large central charge c and a sparse low energy spectrum. This …

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 There are various definitions of the concept of complexity in Quantum Field Theory
as well as for finite quantum systems. For several of them there are conjectured holographic …

We consider toy models of holography arising from 3d Chern-Simons theory. In this context
a duality to an ensemble average over 2d CFTs has been recently proposed. We put forward …

A bstract We construct new Euclidean wormhole solutions in AdS d+ 1 and discuss their role
in UV-complete theories, without ensemble averaging. The geometries are interpreted as …

A bstract We study a precise and computationally tractable notion of operator complexity in
holographic quantum theories, including the ensemble dual of Jackiw-Teitelboim gravity and …

The Hungarian physicist Eugene Wigner introduced random matrix models in physics to
describe the energy spectra of atomic nuclei. As such, the main goal of random matrix theory …

We develop a class of matrix models that implement and formalize the eigenstate
thermalization hypothesis (ETH) and point out that, in general, these models must contain …
