Theory of Many Body Processes in Chemical Physics

在化学部理论和计算物理化学计划的这个项目中，莱因哈特将开展研究，从根本上探索混沌哈密顿动力学与光谱学、化学动力学、半经典量子化和对应原理等问题的关系。重点是发展新的数学和计算方法，涉及电子-原子碰撞，导致电离和/或解离的原子和分子的光吸收，以及强交流和直流外场中原子的结构；以及与皮秒时间尺度上的实验相关的吡咯模式特定激发后的凝聚相分子间动力学。

In this project in the Theoretical and Computational Physical Chemistry Program of the Chemistry Division, Reinhardt will carry out research which will fundamentally explore the relation of chaotic Hamiltonian dynamics to problems of spectroscopy, chemical dynamics, semi-classical quantization, and the correspondence principle. The emphasis will be on development of new mathematical and computational approaches relating to electron-atom collisions, atomic and molecular photoabsorption leading to ionization and/or dissociation, and the structure of atoms in intense ac and dc external fields; and condensed phase intermolecular dynamics following mode specific excitation of pyrrole as related to experiments on a picosecond time scale.
