Outline of Research at the Start

レーザー光源技術や時間・空間分解測定法の急速な発展により,固体物性の高速光制御に関する研究は新たな局面を迎えている。本研究では,時間的・空間的な階層性の観点から強相関多体系において光照射により誘起されるダイナミクスの理論解析を実施する。これによりナノメートル程度の微視的量子状態とサブマイクロメートル程度の半巨視的秩序状態の関係を明らかにし,物性の新たな光制御法の構築を目指す。

Outline of Final Research Achievements

In this research project, we conducted a theoretical study focusing on the temporal and spatial dynamics induced by light irradiation in strongly correlated many-body systems, particularly the transient processes in which macroscopic ordered states are formed from microscopic quantum states. In magnetic materials with spatial inversion symmetry, we found that non-thermal states of electrons driven by optical fields stabilize various magnetic ordered states, such as spin scalar chiral states and 120-degree Neel states, through mechanisms different from those known in equilibrium systems. Additionally, we revealed that such optical driving of electrons enables the control of staggered magnetization directions in antiferromagnetic materials and allows for the spectroscopy of quasiparticle band structures even in strongly correlated systems.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は,レーザーなどの光照射によって生じる非平衡状態において,平衡状態の性質からは予想されない新奇な現象が生じることを具体的に示しており,非平衡系の豊かな物理の一端を明らかにしたものである.この知見は,非平衡物理学や光物性物理学における新たな研究の方向性を与えるだけではなく,将来的には従来の限界を超えた新たなデバイスの基礎原理にも繋がる可能性があるものと期待される.
