Outline of Final Research Achievements

The main researcher proposed laser-driven structural change in materials by performing the first-principles calculations. He also proposes enhancement of laser field near some materials, and found enhancement of laser decomposition of water molecules when the molecules are located near two-dimensional materials, like as graphene, as well as near the carbon nanotubes. Moreover, he found preservation of dynamical coherence of pulse-excited electrons in an isolated molecule within a short time.
Meantime, the collaborating researcher searched current development of laser instruments for short-pulse with high-power as well as applications to laser-cutting and laser-ablation of materials especially in liquid environment by attending international conferences and exhibitions.

Academic Significance and Societal Importance of the Research Achievements

従来から熱平衡状態の延長で理解されてきたレーザーによる物質構造変化の素過程を、電子励起が引き起こす熱的非平衡ダイナミクスととらえ、しかもある程度の予測を計算機を用いたシミュレーションで行えることを明らかにした。また、近年注目されている励起電子のコヒーレントなダイナミクスが、複数個の原子からなる孤立分子内でも見られる可能性をシミュレーションで示唆し、新規な量子デバイスの要素技術を先導すると期待される。最後に、物質中の非平衡ダイナミクスを誘起するに足りる性能を持つレーザー装置開発や材料加工の応用が進んでいることを把握し、理学と工学の両方に本研究で得た知見を応用したさらなる発展があることが分かった。
