Interplay of electron-phonon nonadiabaticity and Raman scattering in the wavepacket dynamics of electron-phonon-photon systems

Abstract

Ultrafast wavepacket dynamics of electron-phonon-photon systems is studied by numerical calculations. When nonadiabaticity of electron-phonon systems is taken into account, Raman scattering process plays an important role in the dynamics of the system. We found that the interplay of the electron-phonon nonadiabaticity and the Raman scattering determines the wavepacket motion particularly in the vicinity of the conical intersection of adiabatic potential energy surfaces, which shows that we should consider this effect in order to reveal the photoexcitation/deexcitation process of materials in femtosecond time scale.
