Elucidation of the mechanisms for collective motions of complex molecular systems with hierarchical structures

本研究主要探讨具有高度有序等级结构和功能的复杂分子系统的大振幅集体运动机制。我们发现，特定的模式耦合和内部（振动）模式之间的能量转移支配的原子/分子团簇的结构转变的发生和速率。我们还仔细研究了DNA的弹性性质，阐明了DNA高阶结构手性自发选择的机制。

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.
