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.

研究激光驱动的少粒子系统的关联动力学。我们将主要关注强激光场中的原子和小分子。在原子中，电子-电子关联效应将通过各种方法的比较来分析，而在激光-分子相互作用中，主要关注的是量子核动力学和电子-核纠缠的非玻恩-奥本海默描述。该项目的目的是提供深入了解如何驱动的少粒子和多粒子系统可以通过理论方法超越单活性粒子和平均场描述的一般问题。
