Realistic exciton-phonon coupling is too weak for Dyakonov-Perel motional narrowing in MoS2; full-Brillouin-zone intervalley scattering shortens valley depolarization 3–4× to ~50 fs (300 K) and ~130 fs (10 K).

Exciton valley depolarization in monolayer MoS2: non-Markovian quantum dynamics, intervalley scattering, and the breakdown of the Dyakonov-Perel mechanism
