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 …

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 …

Recent work has shown that loop corrections from massless particles generate 3 2 log T
Hawking corrections to black hole entropy which dominate the thermodynamics of cold near …

A bstract We study four-derivative corrections to five-dimensional minimal gauged
supergravity. We evaluate the on-shell action of the AdS 5 black hole solution with two …

A bstract In this paper, we use the Karch-Randall braneworld to study theories of quantum
gravity in two dimensional (nearly) anti-de Sitter space (AdS 2). We focus on effective …

A bstract We study the cohomology of local BPS operators in\(\mathcal {N}\)= 4 Yang-Mills
theory. The finite N cohomologies consist of the graviton part (subject to the stringy exclusion …

Reproducing the integer count of black hole micro-states from the gravitational path integral
is an important problem in quantum gravity. In this paper, we show that, by using …

A bstract We revamp the constructive enumeration of 1/16-BPS states in the maximally
supersymmetric Yang-Mills in four dimensions, and search for ones that are not of multi …

We study the gravitational description of extremal supersymmetric black holes. We point out
that the $ AdS_2 $ near horizon geometry can be used to compute interesting observables …

A bstract We study how the microstates of BPS sectors in string theory are organized in the
dual U (N) gauge theory. The microstates take the form of a coherent sum of stacks of branes …
