一、个人简介

I am interested in physics, mathematics and natural philosophy and have published research papers in both physics journals and mathematics journals. Although I was often regarded by my colleagues as a mathematician, all my works are motivated by fundamental questions in physics or natural philosophy. My long term goals are to develop a new calculus for quantum many-body theory or quantum field theory (including a new paradigm of phase transitions) and to gain a deeper understanding of the origin of space and time. A summary of my past research can be found here: LK_research.pdf. I provide a list of topics that I am interested in.


Physics: topological/conformal/quantum field theories, quantum phases in condensed matter physics (including topological orders, SPT/SET orders, spontaneous symmetry-breaking orders, quantum liquids), phase transitions and quantum gravity.


Mathematics: vertex operator algebras and their representations, conformal/topological nets, operator algebras, higher categories, higher algebras, higher representations, factorization homology, higher homotopy theory and geometric Langlands correspondence.
