Electronic quantum material is the playground. In ordinary materials like metal, it's a miracle that the behavior of 1023 electrons can be described as the motion of a single particle. Electronic quantum materials break this paradigm due to strong interplay between multiple degrees of freedom, leading to novel phenomena such as superconductivity, (anti)ferromagnetism, ferroelectricity, metal-to-insulator transitions, and density waves. These phenomena are the foundation for the next generation of quantum technologies. We design and realize new electronic states with novel properties through precise control of materials synthesis pathways, using techniques such as energy landscape engineering, thermodynamic control, and material chemistry methods. This allows for the stabilization of new phases of matter and versatile control over quantum electronic states.

Understanding and control are the goals. My research aims to not only discover new phases of matter but also to establish a fundamental understanding of the underlying physics that governs them. The ultimate goal is to gain precise control over material properties by manipulating their quantum states. We employ a wide range of control to manipulate the electronic ground state though interplay between multiple degrees of freedom, for examples, strain is an effective knob to control atomic spacing, direct tuning orbital overlaps; doping introduces additional carriers as well as chemical disorders that perturb electronic phases; laser excitation shakes the electron distribution in new non-equilibrium states. By mastering these knobs, we can unlock the full potential of electronic quantum materials and pave the way for a new era of quantum devices.
