Electronic/Magnetic Properties of Quantum Materials

We investigate electronic structure, magnetism, and related quantum properties of materials, including spin and valley physics, topological states. In addition, we study functional properties relevant to energy and spintronics, such as photocatalysis, thermoelectric and thermal transport, optoelectronic responses, and energy storage applications. Our goal is to reveal, control, and engineer emergent quantum phase and multifunctional properties in complex materials.
