Dynamics in complex systems subjected to strong perturbations combines two of the most challenging problems of theoretical physics, which are few-/many-body physics and non-perturbative dynamics. To date, there exist little theoretical tools that can handle this problem. Over the past few years the group of Dr. Brabec has developed a novel approach called multi-configuration time-dependent Hartree-Fock (MCTDHF). MCTDHF is the first method that can calculate the dynamics of few-electron systems in the presence of strong perturbations, taking properly account of correlation. Therewith, it opens the opportunity to theoretically investigate a wide spectrum of correlated few electron phenomena that were not accessible so far.

受到强扰动的复杂系统动力学结合了理论物理中两个最具挑战性的问题，即少/多体物理和非微扰动力学。到目前为止，几乎没有理论工具可以处理这个问题。在过去的几年里，Brabec博士的团队开发了一种新的方法，称为多配置时间依赖Hartree-Fock（MCTDHF）。MCTDHF是第一个可以计算强扰动下少电子系统动力学的方法，适当地考虑了相关性。因此，它打开了一个机会，从理论上研究了广泛的相关的少数电子现象，目前还没有访问。
