Outline of Research at the Start

本研究では、強相関電子系物質の物性を反映する量子自由度の長距離秩序構造ダイナミクスを、フェムト秒からピコ秒の時間幅を有する硬・軟X線パルスを複合的に利用した時間分解X線回折・散乱法により包括的に明らかにする。これにより、強相関電子物性が光照射で高速かつ高効率に変化する光誘起相転移現象の本質を統一的に理解し、応用に向けた制御方法や新奇な動的機能性を有する物質の探索および創成に明確な指針を与えることを目指す。

Outline of Final Research Achievements

To reveal the long-range ordered electronic and lattice structures in the non-equilibrium states that reflect physical properties of strongly correlated electron systems, we have conducted time-resolved X-ray diffraction and scattering measurements. These measurements utilized a combination of hard and soft X-ray pulses with femtosecond and picosecond durations, depending on the observed time scales and quantum degrees of freedom. By combining synchrotron radiation with a variable repetition rate laser system, we have implemented a time-resolved soft X-ray measurement system capable of measuring at a sampling frequency more than ten times higher than conventional systems. Furthermore, we clarified the overview of non-equilibrium dynamics in which photoexcitation triggers changes in the electronic state, leading to coherent modulation of the quantum ordered state coupled with the phonon, and subsequently developing into a macroscopic phase transition.

Academic Significance and Societal Importance of the Research Achievements

本研究で開発した高サンプリング周波数時間分解軟X線計測システムにより、従来のシステムでは微弱な信号で計測が困難であった物質系への適用が可能となり、対象物質や測定環境が大幅に拡大した。レーザーや放射光、X線自由電子レーザーの複合利用で解き明かされた、協同的に相互作用した量子自由度の非平衡ダイナミクスの新たな知見は、光パルスを利用した新規な超高速物性制御の手法や新規な動的機能性を有する物質の探索および創成に明確な指針を与えるだけでなく、その技術を利用した次世代超高速スイッチング通信デバイスの応用展開に向けて、飛躍的に研究開発が加速されると期待される。
