为了在分子尺度上理解物理过程,通过波包传播来研究潜在的动力学是很方便的。过去已经发展了许多不同的传播方案,从数值上精确的标准方法,只能处理非常小的系统到近似的系统,如依赖于时间的Hartree方法(TDH)。其中一种方法,多组态依赖时间的Hartree方法(MCTDH)已经在海德堡发展起来,它已经证明了它能够完全量子力学地和高精度地处理大系统(>9个自由度)。
For the understanding of physical processes on a molecular scale it is convenient to study the underlying dynamics by wavepacket propagation. Many different propagation schemes have been developed in the past, reaching from the numerically exact standard method, that can only treat very small systems to approximate ones like the time dependent Hartree method (TDH). One of those methods, the multi-configuration time-dependent Hartree (MCTDH) method, has been developed in Heidelberg and it has proved its capability to treat large systems (> 9 degrees of freedom) fully quantum mechanically and with high accuracy.
