报告摘要:

Modern techniques of ultrafast laser spectroscopy and ultrafast X-ray (electron diffraction), which are capable to achieve femtosecond and even attosecond time resolution and high spatial resolution, provide excellent probes of chemical reactions in various molecular systems. The constantly increasing body of experimental data on molecular and chemical reaction mechanisms necessitates the development of accurate theoretical methods, which enable us to explain spectroscopic signals of molecular systems as well as their associated structural changes in terms of the underlying nuclear and electronic dynamics. In the past years, I have developed various numerical methods based on variational wave function, quantum master equation and stochastic Schrödinger equation for the efficient simulation of quantum dynamics and nonlinear spectroscopic signals. My goal is to build a direct link between theory and experiment, to reveal the reaction mechanisms of photophysical and photochemical processes, and finally to provide important theoretical guidance for the design of efficient optoelectronic devices.
