We study condensed matter physics and many body problems, such as strongly correlated electron systems, high-Tc superconductivity, Mott metal -insulator transition, topological materials, Dirac electron systems in solids, thermoelectric materials with large response, organic conductors, and magnetic systems with frustration and/or spin-orbit interactions.

Each member chooses their research theme based on their own interest, and you will not be forced to study something that is not interesting for you. Although the specific research topics of each of us are different, we know each other well through regular group seminars and daily conversations. Ideas and research methods from slightly different fields are sometimes useful for our own research.

Recent research themes are listed bellow:

• Spin current in topological materials

• Meissner effect of Dirac superconductor

• Magnetic phase diagram of the Kitaev model on the hyperkagome lattice

• Basic theories for thermoelectricity (Phason drag, Paramagnon drag, etc.)

• Classification theory of nodal line semimetals

• Quantum spin liquid on the pyrochlore lattice

• Magnon excitation of Skyrmion lattice
