Outline of Final Research Achievements	The administrative group has been organizing and managing the establishment of a new academic field that integrates different fields, such as condensed matter physics, photochemistry, laser engineering, physical chemistry, nanomechanical engineering, and molecular fluid dynamics, by effectively and organically promoting intergroup joint research and establishing a framework for a new academic field that can integrate advanced knowledge and technologies dispersed in different fields. This has revealed "measurement, observation, and detection of physical properties that are impossible with other approaches," "methods for (hierarchical) structure fabrication through artificial manipulation of phase transitions and self-assembly such as crystallization," and "unprecedented methods for controlling chemical processes through physical manipulation of molecules," etc., and has made visible "individual, selective, and direct" manipulation of nanomaterials.
Free Research Field	ナノ光科学
Academic Significance and Societal Importance of the Research Achievements	本領域の成果は、「力学的運動とリンクさせることで微視的特性を探り出す」新しい物質科学上の方法論に加え、「微視的構造まで制御された多様な静的・動的秩序構造実現」への基礎技術、さらに「化学反応制御、分子計測の高度化」など多様な応用技術に結びつくと期待される。また、その展開は、光と物質のインタープレイから生じる様々な現象を対象とした光科学の中でも、光そのものの観測に基礎を置く従来の光科学とは異なる方向への展開となり、新たな開拓領域へ結びつく点でも重要な学術意義を持つと考えられる。さらに得られた成果は、将来のエネルギー技術や創薬技術等に波及していくと期待され、社会的にも大きな意義があると期待される。
