The Laboratory of Novel Quantum Materials focuses on the research of quantum materials that host exotic physical phenomena emerging from microscopic quantum effects. As a cutting-edge branch of condensed matter physics, this field also ranks among the most vibrant interdisciplinary research areas.

Our research covers a complete full-chain workflow: designing new material structures based on structural chemistry principles, achieving sample synthesis and crystal growth via materials science methodologies, and interpreting the intrinsic physical properties of materials from the perspective of condensed matter physics. We strive to explore novel mechanisms and potential applications of quantum materials at the fundamental level.

Our research group plans to recruit two PhD students every year and warmly invites applications for postdoctoral fellow positions. If you have a strong interest and genuine passion for condensed matter physics and materials physics, with solid academic fundamentals and outstanding hands-on capabilities, you are welcome to contact us by email for further communication. Join us to explore the fascinating world of quantum materials together!
