| Outline of Final Research Achievements |
We have conducted experimental studies on "quantum liquid crystals (QLC)," a group of materials with fluidic and anisotropic electronic states. QLCs are characterized by their self-organized electronic states and fast giant response to an external field. We have revealed their unique magnetic structures using synchrotron radiation and neutrons. We have also successfully developed real-space observation techniques such as ultrafast time-resolved transmission electron microscope and quantum spin microscope. We have also elucidated the high-frequency dynamics of spin-based liquid crystal structures. Furthermore, we developed optical experimental techniques such as time-resolved angle-resolved photoemission spectroscopy using higher-order harmonic lasers and topological light waves to investigate electronic states. The above achievements will directly lead to the elucidation of the peculiarities of QLCs and the development of their functionalities.
