中文摘要Abstract: Nonadiabatic dynamics is ubiquitous in photo-physical and photo-chemical processes. The description of nonadiabatic transitions requires the treatment of coupled electron-nuclei motions. Exact quantum dynamical calculations, due to the insurmountable computational scaling with the size of the system, are only applicable to small molecular systems. In recent years, several approximat methods based on the quantum-classical dynamics were proposed to describe the nonadiabatic dynamics of polyatomic molecular systems. This article provides a concise review of different versions of quantum-classical dynamics approaches including the classical Ehrenfest method, the surface-hopping technique, and the mixed-quantum-classical dynamics in terms of the Winger representation. The pros and cons of the on-the-fly numerical implementation of these schemes combining the ab initio electronic structure calculations are discussed and perspectives on further development of quantum-classical treatment of nonadiabatic dynamics are given.
