摘要:Nonadiabatic dynamics widely exist in photophysics, photochemistry and photobiology. We tried to develop theoretical approaches to study the photoinduced nonadiabatic dynamics.
1. We combined the doorway-window representation of the nonlinear response theories and ab initio nonadiabatic dynamics to simulate the time-resolved pump-probe spectra.
2. We tried to combine deep leaning method and numerical accurate quantum dynamics approach to simulate the long-time quantum evolution of open quantum system. This approach allows us to obtain the evolution of reduced density matrix of open quantum system with a low computational cost.
3. We showed the possibility to analyze the geometrical evolution of trajectory-based nonadiabatic molecular dynamics by unsupervised machine learning. These approaches allow us to extract the major molecular motion in the excited-state dynamics simulations.
