A solvable model for strongly interacting nonequilibrium excitons

Proceedings of the National Academy of Sciences, Volume 122, Issue 11, March 2025.
SignificanceExcitons, bound states of electrons and holes, can be formed by shining a laser on a semiconductor. Recent experiments have suggested that sufficiently intense laser excitation applied to a WS2-WSe2bilayer creates a “Mott insulator” of …
