Electron-phonon dynamics in an ensemble of nearly isolated nanoparticles
Electron-phonon dynamics in an ensemble of nearly isolated nanoparticles
We investigate the electron population dynamics in an ensemble of nearly isolated insulating nanoparticles, each nanoparticle modeled as an electronic two-level system coupled to a single vibrational mode. We find that at short times the ensemble-averaged excited-state population oscillates but has a decaying envelope. At long times, the oscillations become …
