Biography
Qiang Li is a SUNY Empire Innovation Professor at Stony Brook University and a fellow of American Physical Society (APS), with a joint appointment at Brookhaven National Laboratory (BNL) leading the Advanced Energy Materials Group, where he has been a lead principal investigator of superconducting and topological quantum materials program, funded by the US DOE Office of Basic Energy Science, for two decades. With his collaborators, he discovered two-dimensional superconductivity in stripe ordered high temperature superconductor (HTS) in 2007, and chiral magnetic effect in condensed matters in 2014. He graduated from University of Science and Technology of China (Hefei) with a bachelor’s degree in science in 1986 and came to the US on the CUSPEA (China-U.S. Physics Examination and Application) program under direction of Prof. T. D. Lee, a Nobel laureate. He received his PhD in physics from Iowa State University in 1991.

Research Statement
Qiang Li’s Quantum Materials Physics group is primarily focused on physics and applications of quantum materials in energy and quantum information systems. This group uses a combined materials synthesis, characterization and theoretical modeling approach to explore quantum states of matter. Synthesis effort includes single crystal and epitaxial film growth of a variety of quantum materials from superconductors to topological semimetals/insulators, and high-pressure synthesis of novel materials. Multiple characterization techniques are used in this group to characterize transport and thermodynamic properties of quantum materials under various external stimuli, such as light, temperature, magnetic field, pressure and in-situ tunable strain. Photon and electron spectroscopic experiments, some of which are carried out at national synchrotron light sources, are performed to explore electron and phonon band structures. Theoretical modeling uses first-principles and effective Hamiltonian methods. Recently, this group has been particularly interested in understanding and control of topological phase transitions and unconventional superconductivity, with an increased effort in quantum device fabrication and characterizations. The development of scalable superconducting and thermoelectric materials and devices is a longstanding effort of this group for applications in next generation of electric machines, electricity transmission, energy conversion and storage.
