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.

受到强烈扰动的复杂系统中的动力学结合了理论物理学中最具挑战性的两个问题，这些问题是很少/多体物理学和非扰动动力学。迄今为止，几乎没有理论工具可以解决此问题。在过去的几年中，Brabec博士的小组开发了一种新颖的方法，称为多构型时间依赖性Hartree-fock（MCTDHF）。 MCTDHF是第一种可以在存在强扰动的情况下计算几电子系统动力学的第一种方法，并正确地考虑了相关性。因此，它为理论上研究了迄今为止无法访问的几种电子现象的广泛相关的机会。
