The project involves theoretical study of two complementary processes. The first is strong-field photoionization, in which electrons are detached from atoms in intense laser light. Studies in this area involve extensive computer modeling and focus primarily on understanding the dynamics of double ionization. The complementary area of study is photorecombination, in which electrons reattach to atoms and emit light. Studies in this latter area combine the development of a mathematical formalism with computer application for examining photorecombination processes that can occur in high-temperature plasmas.

该项目涉及两个互补过程的理论研究。 第一个是强场光电离，其中电子以强烈的激光从原子脱离。该领域的研究涉及广泛的计算机建模，并主要关注理解双电离的动力学。互补的研究领域是光结合物，其中电子重新构成原子并发出光。后一个领域的研究结合了数学形式主义的发展与计算机应用，用于检查可能发生在高温等离子体中的光结合过程。
