Research Abstract

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.
