Research Interests

My research work encompasses frustrated magnets, topological phases of matter, Floquet topological systems, and machine learning. I also have a keen interest in the application of quantum field theory to condensed matter systems. I have worked on different branches of condensed matter physics ranging from instantons, hard-core bosons, quantum spin ice, to topological insulators and semimetals. In recent years, my research has focused mainly on topological phases of matter in bosonic as well as fermionic systems. In particular, the majority of my research has been devoted to developing the notion of topological semimetals and insulators to bosonic systems in quantum magnetism. I have made tremendous progress in this field, accompanied by numerous well-recognized sole authored publications. Below is the list of selected publications.
