First-principles ultrafast exciton dynamics and time-domain spectroscopies: dark-exciton mediated valley depolarization in monolayer ${ m wse}_2$

HIGHLIGHTS

• who: Hsiao-Yi Chen from the Department of Technology, Pasadena, California, USA have published the paper: First-principles ultrafast exciton dynamics and time-domain spectroscopies: Dark-exciton mediated valley depolarization in monolayer ${
  m WSe}_2$, in the Journal: (JOURNAL) of 21/Dec/2022
• what: The authors show calculations of ultrafast exciton dynamics and related time-domain spectroscopies using ab initio exciton-phonon (ex-ph) interactions together with an excitonic Boltzmann equation. Starting from the nonequilibrium exciton populations the authors develop simulations of time-domain absorption and photoemission spectra that take into account electron-hole correlations . . .
