Theory of laser-assisted and laser-induces processes in few-electron atomic and molecular systems

在这个项目中，将研究激光场与双中心库仑系统相互作用的两种不同但相关的实现：激光辅助离子原子碰撞和强场中双原子分子的破碎：即激光诱导的半碰撞。在这两种情况下，处理将基于电子的非微扰量子描述和原子核的经典描述。重点将从时变密度泛函理论的角度详细分析电子-电子相互作用在多电子系统中的作用。这项研究有望揭示与时间相关的单电子和多电子动力学，特别是它们可能被适当的激光场操纵和最终控制的可能性。

In this project two different but related realisations of laser-field interactions with two-centre Coulomb systems will be studied: laser-assisted ion-atom collisions and the fragmentation of diatomic molecules in intense fields: i.e., laser-induced half-collisions. The treatment will be based in both cases on a nonperturbative, quantal description of the electrons and a classical description of the nuclei. Emphasis will be given to a detailed analysis of the role of the electron-electron interaction in many-electron systems from the perspective of time-dependent density functional theory. The study is expected to shed light on time-dependent one- and many-electron dynamics and, in particular, on their possible manipulation and ¿ ultimately ¿ control by suitable laser fields.
