Jian Li’s research focuses on condensed matter systems that exhibit nontrivial topological electronic properties. In particular, he is interested in the physics of topological superconductivity and the associated Majorana quasi-particles, the latter being potentially useful to realize fault-tolerant quantum computing.

Dr. Li, working together with a team of experimentalists based at Princeton University, discovered Majorana quasi-particles in iron chains grown atop superconducting lead. They provided compelling evidence for the observation of these long-sought-after, esoteric particles with scanning tunneling microscopes. Dr. Li developed a theoretical framework for an in-depth understanding of the system involving aligned magnetic adatoms and conventional superconductors, and further established such a system as a new platform to engineer topological superconductivity not only in one dimension but also in higher dimensions. Based on this platform, Dr. Li and his collaborators have made proposals that will hopefully reveal one of the most fascinating features, namely nonabelian braiding statistics, of Majorana quasi-particles in the near future.

“Physics for me is about connecting elegant concepts encoded in equations to intricate signals produced in equipment. I strive to grasp the elegance, the intricacy, and the truth in-between.”
