MSE Areas: Novel electronic and magnetic materials; single-crystal synthesis; physics of complex oxides; high-field, low-temperature, and high-pressure material properties

Our research is driven by two interconnected thrusts -- Discovery of New Quantum Materials and Control of Novel Quantum States. It encompasses a methodical search for new quantum materials, especially new 4d- and 5d-electron based materials, and a systematic effort to elucidate and control novel quantum states in these materials. The diagram on the right illustrates our proven research protocol. Our group is equipped with (1) advanced techniques and comprehensive facilities to synthesize bulk single crystals of a wide range of materials, in particular, transition metal oxides and chalcogenides, and (2) a wide spectrum of tools for experimental studies of structural, transport, magnetic, thermal and dielectric properties as functions of chemical composition, temperature, magnetic field, and pressure. Measurements are often carried out at extreme conditions, i.e., ultralow temperatures, high magnetic fields and high pressures. We have also established broad collaborations with leading scientists in the US and around the world.
