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

我们将研究激光驱动的小粒子系统的关联动力学。我们将主要关注强激光领域中的原子和小分子。虽然原子中的电子-电子关联效应将通过比较各种方法来分析，但激光-分子相互作用中的主要问题将是量子核动力学和电子-核纠缠的非Born-Oppenheimer描述。该项目旨在提供对一般问题的洞察，即如何通过理论方法访问受驱动的少粒子和多粒子系统，而不仅仅是单活动粒子和平均场描述。

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.
