Random matrix theory of integrability-to-chaos transition
Ben Craps, Marine De Clerck, Oleg Evnin +1
The statistics of gaps between quantum energy levels is a hallmark criterion in quantum chaos and quantum integrability studies. The relevant distributions corresponding to exactly…

Area terms and entanglement entropy in the string theory
Ben Craps, Marius Gerbershagen, Maxim Pavlov +1
We study entanglement entropy in the low-energy effective field theory of two-dimensional string theory as well as in the singlet sector of the dual matrix quantum mechanics.…

Phase-space localization at the lowest Landau level
Ben Craps, Marine De Clerck, Oleg Evnin +1
We consider bosons with weak contact interactions in a harmonic trap and focus on states at the lowest Landau level. Motivated by the known nontrivial phase-space topography of the…
