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…
