报告题目:Quantum mechanical description of multielectron motion in atoms and molecules: From wave function theory to effective potential theory

报告人:Tsuyoshi Kato, The University of Tokyo

报告人简介:

Tsuyoshi Kato has been an associate professor in the department of chemistry , the University of Tokyo since 2006. He obtained his PHD in chemistry from Tohoku University in 1996. He was a postdoctoral researcher in the Institute of  Atomic and Molecular Sciences (IAMS) in Taiwan, China. From 1996 to 1999, he worked as a domestic researcher in the Electro technical Laboratory of Japan Science and Technology Corporation. In 2002, he became a research fellow in the department of Chemistry, Tohoku University. In 2016, he was appointed as an visiting associate professor in the department of Theoretical and Computational Molecular Science, Institute for Molecular Science (IMS).

摘要:

Recent advances in ultra-short and intense laser pulse generation technology have enabled highly nonlinear interactions between atoms and molecules and laser field in the near infrared region. One of the most well-known phenomena may be the knee structure in the excitation light intensity dependence of non-sequential double ionization. In order to describe such nonperturbative electronic response, it is necessary to use a wave function that incorporates electron correlation beyond the time-dependent Hartley-Fock method. In fact, the knee structure can be reproduced by the time-dependent multi-configuration wave function. To understand the correlated electron motion, Prof. Kato has recently focused on time-dependent effective potential theories. In this talk, he will introduce the multi-configuration time-dependent wave function theory that they have been involved to develop, and the current status of the development of the time-dependent effective potential theories to understand the dynamical electron correlation.
