Magnetically tunable exciton valley coherence in monolayer WS${}_2$ mediated by the electron-hole exchange and exciton-phonon interactions

Kang Lan, Shijie Xie, Jiyong Fu +1

We develop a model, which incorporates both intra- and intervalley scatterings to master equation, to explore exciton valley coherence in monolayer WS${}_2$ subjected to magnetic fie…
