Research Interests

Condensed Matter Physics – Material Physics – Material Simulation-Device Physics

The main aim of our research is to generate new multi-functional devices for the development of disruptive technologies based on the synthesis and exploration of unprecedented physics of novel materials. The focus is to synthesize novel materials to realize low-dissipation or dissipationless devices including magnetic semiconductors for low-power spintronics, magnetic oscillations (e.g., quantum Hall effects, quantum spin Hall effect) with a low magnetic field for a dissipationless current, and condensation (e.g., high-Tc superconductivity, BEC condensation, quantum spin liquids). These quantum phenomena usually appear at low temperatures, which impede the practical applications of these exotic physics. Therefore, our ambitious targets are to induce the quantum phenomena at room temperature and realize quantum devices operating in daily-life conditions.
