INTRODUCTION OF LABORATORY
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.
