Dr. Kaixin Hu | Harbin Institute of Technology | China
Dr. Kaixin Hu is an emerging theoretical physicist whose research focuses on topological phases, non-Hermitian systems, and quantum materials. He earned his B.Sc. in Physics and a double major in Business Administration from Yanbian University (2015–2019), followed by an M.Sc. in Theoretical Physics from the same institution (2019–2022), where he received multiple academic honors including the Physics Talent Scholarship, National Encouragement Scholarship, and Excellent Master’s Thesis Awards from both Yanbian University and Jilin Province. Currently pursuing his Ph.D. in Theoretical Physics at the Harbin Institute of Technology (2022–2026), Dr. Hu continues to distinguish himself as an Outstanding Student (2025). His research explores the fundamental principles of quantum topology, phase transitions, and their realizations in topolectrical and circuit quantum electrodynamic lattices. Dr. Hu has published 13 peer-reviewed papers in internationally recognized journals such as Physical Review A, Advanced Quantum Technologies, and Chinese Journal of Physics, with 35 citations and an h-index of 3. His notable contributions include studies on topological phase transitions and edge states in quasi-three-dimensional circuit QED lattices, boundary criticality in Chern insulators, and anomalous phase transitions in nonreciprocal class-D systems. Beyond research, he has demonstrated excellence in scientific innovation and leadership, earning numerous accolades such as the First Prize in the Jilin Province College Student Mathematical Modeling Competition and the Special Contribution Award from Yanbian University. Through his work at the intersection of condensed matter physics and quantum technology, Dr. Hu is advancing theoretical frameworks that deepen the understanding of next-generation topological quantum systems.
