| Research Abstract |
This study focused on the mechanisms for large-amplitude collective motions of complex molecular systems with highly-organized hierarchical structures and functions. We found that specific mode coupling and energy transfer among internal (vibrational) modes govern the onset and rates of structural transitions of atomic/molecular clusters. We also scrutinized elastic properties of DNA and clarified the mechanisms for the spontaneous selection of chirality of higher-order structures of DNA.
