Abstract

A tunable optical switching process based on spin valley quantum coherence in a hybrid system consisting of a WS2 monolayer and a metallic nanoantenna is investigated. This process is induced by plasmonically-mediated intervalley exciton-plasmon coupling which is shown to be quite resilient against ultrafast valley decoherence.
