Giant Rydberg excitons

Probing quantum chaos

Nature Materials volume 15, pages 702–703 (2016)Cite this article

Subjects

Giant Rydberg excitons reveal signatures of quantum chaotic behaviour in the presence of time-reversal symmetry breaking enforced by the background solid-state lattice, and they provide a new mesoscopic platform for fundamental studies of quantum chaos.
