Research

Outline

The Electronic State of Solids Laboratory aims to create novel crystals exhibiting interesting physical phenomena (Physics + Crystal = Physicrystal). 

The discovery and elucidation of new phenomena and novel quantum phases, such as superconductivity, have greatly advanced condensed matter physics. The development of new materials has played a major role in this process. For example, the discovery of high-Tc cuprate superconductors and Kitaev spin liquid candidates are known as important results in condensed matter physics. We hope to contribute to the progress of condensed matter physics through the development of new quantum materials and the experimental establishment of various quantum phenomena predicted by theories.

In particular, we are working on the following themes, focusing on the development of new materials.

• Exploration of frustrated magnets and precise evaluation of their physical properties
• Exploration, visualization, and cross-correlation study of magnetic skirmion materials
• Development and characterization of odd-parity multipole materials
• Search for exotic superconductors
