Research Interests:
My research interest is focused on the exploration of emergent quantum materials and phenomena under high-pressure extreme conditions. On the one hand, we synthesize novel functional and quantum materials by using the start-of-the-art multianvil system (6/8-type), which can generate pressures over 25 GPa and temperatures over 1500 C. By using this approach, we have obtained novel S=1 quantum spin liquid candidate in the high-pressure phases of Ba3NiSb2O9, a d-electron heavy-fermion compound CaCu3Ir4O12, and a Slater insulator SrIr1-xSnxO3 with strong spin-orbit coupling. On the other hand, we explore the exotic quantum phenomena of strongly correlated electron systems by performing in-situ measurements of physical properties with a cubic-anvil-type apparatus, which combines the following extreme conditions: Pmax ~ 15 GPa, Tmin ~ 1.5 K, and Hmax ~ 9T. We discovered the first Cr- and Mn-based superconductors, CrAs and MnP, by suppressing their helimagnetic order under high pressures. We expect to uncover more interesting materials and exotic phenomena under high-pressure extreme conditions.
