Abstract:
The symmetry of crystal structures plays a crucial role in determining the physical properties of crystals. Unconventional superconductivity often emerges in superconductors where inversion symmetry is intrinsically or artificially broken (e.g., via introducing glide planes). Furthermore, breaking time-reversal symmetry in such systems may lead to the discovery of topological superconductivity hosting Majorana fermions. Therefore, the exploration of novel noncentrosymmetric superconductors represents a significant and challenging research direction in condensed matter physics. In this talk, I will present our recent progress in design of unconventional superconductivity through manipulating inversion symmetry in layered materials [1].

Biography:
Yanfeng Guo is a Professor at the School of Physical Science and Technology, ShanghaiTech University. He completed his Ph.D. program at the Institute of Physics, Chinese Academy of Sciences, from 2003 to 2008. From 2008 to 2012, he worked as a postdoctoral researcher at the National Institute for Materials Science (NIMS), Japan, followed by another postdoctoral position at the University of Oxford from 2012 to 2015. In July 2015, he joined ShanghaiTech University as a Tenure-track Assistant Professor and was promoted to Tenured Associate Professor in July 2022. His research focuses on the exploration of novel quantum materials, high-quality single-crystal growth, and the study of their physical properties. In recent years, his work has primarily centered on magnetic topological and superconductors. He has published over 260 papers in prestigious journals such as Nature, Nature series journals, and PRX/L, with nearly 7,000 citations (Web of Science).
