Cardy random matrix theory
Marco Ambrosini, Alexandre Belin, Jan de Boer +1
We construct and study a ``Cardy random matrix model'': a random matrix theory whose only input, in a maximal-ignorance prescription, is the constraint of -modular inva…
A Reverse Black Hole Information Problem
Jan de Boer, Jildou Hollander, Andrew Rolph
We study the formation, detection and coarse-graining of black holes in AdS/CFT, with an emphasis on the tension between boundary unitarity and the production of mixed state Hawkin…
Baby Universes in AdS
Alexandre Belin, Jan de Boer
We discuss Euclidean geometries in AdS whose Lorentzian slicing gives rise to closed baby universes with a spatial geometry given by genus surfaces. Our setup only in…
Microstate counting from defects in de Sitter
Jan de Boer, Diego Liska, Kamran Salehi Vaziri
We explore the microscopic origin of de Sitter entropy using a Lorentzian path-integral approach. We construct a Hilbert space whose states are associated with configurations of th…
Modular chaos, operator algebras, and the Berry phase
Jan de Boer, Bahman Najian, Jeremy van der Heijden +1
Modular Berry transport associates a geometric phase to a zero mode ambiguity in a family of modular operators. In holographic settings, this phase was shown to encode nontrivial i…
Multiboundary wormholes and OPE statistics
Jan de Boer, Diego Liska, Boris Post
We derive higher moments in the statistical distribution of OPE coefficients in holographic 2D CFTs, and show that such moments correspond to multiboundary Euclidean wormholes in p…
