In materials in which electrons strongly interact with each other, quantum many-body effect plays an important role. In such strongly correlated electron systems, the electron degrees of freedom, such as charge, spin, and orbital, and the symmetry and topology of the solids cooperatively generate various electronic phases such as Mott insulators, magnetic order, and superconductivity. We would like to design and develop electronic properties based on molecular orbitals in crystals such as transition-metal compounds, rare-earth intermetallics, and molecular conductors. Our research techniques are crystal synthesis, transport-properties and thermodynamics measurements, as well as neutron and synchrotron X-ray scattering at external facilities. The recent research topics include: (1) the development of new materials and functionalities arising from topological magnetic structures, (2) the exploration of novel electronic phases relating to charge, spin, and orbital degrees of freedom in molecular conductors.

You can only continue to do what you want to do on your own. Enjoy proactive research, and even if it seems difficult, you will always be able to see the future If you think about it thoroughly.

Seeing through the eyes of science. I have been doing classical ballet since the first grade of elementary school, and I sometimes think that ballet is connected to physics. If you think about the unique movements of ballet in terms of mechanics and so on, and figure it out, even if you don't have the talent, you can learn it with practice. There are times when I want to run away, but the reaction of the audience will give you an idea of where to do next. I think this applies to research as well. I chose department of engineering because I wanted to find some clue for environmental problems that I learned about in class when I was in elementary school. When I learned about it, I simply thought physics was interesting. Physics for me is a job where I can think about how my ideas can contribute to the world and improve my surroundings while pursuing what I like.
