Research Activities
Our research is focused on various "Quantum Phases of Matter", including unconventional superconductivity, hidden order phase, and quantum spin liquid. We are also studying the anomalous properties associated with the quantum critical point, which is a zero-temperature boundary between two different phases.

Future Plan
A complete understanding of the anomalous quantum phases is one of the most important issues in condensed matter physics, and will provide a strong base for the fundamentals of next-generation functional materials.
Messages to Students
In the field of materials science, we study many aspects of condensed matter. Therefore, even for students just starting with research, there are several opportunities for testing their own original ideas by designing and performing experiments by themselves. No matter how small your idea is, and no matter whether the results are positive or negative, you will find that it is actually the best part of science. Enjoy your research life in our department.
