Laser-induced few-body quantum dynamics beyond the mean-field and Born-Oppenheimer approximations

本文将研究激光驱动的少粒子系统的相关动力学。我们将主要关注强激光场中的原子和小分子。虽然原子中的电子-电子相关效应将通过各种方法的比较来分析，但激光-分子相互作用的主要关注点将是量子核动力学和电子-核纠缠的非玻恩-奥本海默描述。该项目旨在提供关于如何通过超越单活动粒子和平均场描述的理论方法来访问驱动的少粒子和多粒子系统的一般问题的见解。

The correlated dynamics of laser-driven few-particle systems will be investigated. We will focus primarily on atoms and small molecules in intense laser fields. While in atoms electron-electron correlation effects will be analyzed by comparison of various approaches, the main concern in laser-molecule interactions will be the non-Born-Oppenheimer description of quantum nuclear dynamics and electron-core entanglement. The project aims at providing insight into the general problem of how driven few- and many-particle systems may be accessed by theoretical methods beyond single-active-particle and mean-field descriptions.
