The Institute of Applied Physics and Materials Engineering successfully held a seminar on nonlinear transport properties in topological materials on December 09, 2025. Hosted by Prof. Hongchao Liu, the event featured Prof. Hui LI (李惠), Professor from Anhui University and drew a diverse audience of researchers, faculty members, and students—all eager to explore cutting-edge advancements at the intersection of quantum geometry and condensed matter physics.
Prof. Hui Li, a Professor at the Institute of Physical Science and Information Technology, Anhui University. He earned his PhD from the University of Science and Technology of China in 2014, followed by postdoctoral work at the HKUST (2014–2018). He later returned to HKUST as a Research Assistant Professor (2021–2023) before joining Anhui University. His focus on novel magnetotransport properties of low-dimensional quantum materials has made him a leading voice in topological physics research.
The seminar centered on Prof. Hui Li’s latest experimental investigations into how quantum geometry shapes nonlinear transport in topological materials: (1) Controlling second-order nonlinear transport in bulk Weyl semimetal Td-WTe₂ via electric/magnetic fields with observed out-of-plane B-field quantum oscillations; (2) third-order transport in MnBi₂Te₄ flakes from quantum metric/ Berry curvature quadrupoles.
Following the presentation, a lively Q&A session unfolded, with attendees posing questions about experimental design, the potential applications of these nonlinear transport effects, and future directions for research in topological materials. Prof. Hui Li’s expertise in low-dimensional quantum systems—particularly topological materials—enabled rich, technical exchanges that resonated with both early-career researchers and seasoned faculty.
