项目摘要
We have established a wavepacket dynamics method based on the Action Decomposed Function (ADF). This method is not accompanied with the integration of the stability matrix, which prevents large scale calculation because of the required numerical efforts to implement. Considering the geometric structure around the classical trajectory, it was found that quantum effect is appropriately incorporated to go beyond the semiclassical singularity. Applying the method to several systems, that include the one with 100 degrees of freedom, we have confirmed the feasibility of our theoretical framework and established the practical basis for revealing multidimensional molecular quantum dynamics in molecules.
我们建立了一种基于动作分解函数(ADF)的波包动力学方法。该方法没有伴随稳定性矩阵的积分,由于需要进行数值计算,因此无法进行大规模计算。考虑到经典轨迹周围的几何结构,发现适当地结合了量子效应以超越半经典奇点。将该方法应用于包括100自由度系统在内的多个系统,证实了我们的理论框架的可行性,并为揭示分子中的多维分子量子动力学奠定了实践基础。
