Topological matters are new quantum states discovered in recent decades. They are characterized by the topological invariants of the electron wavefunctions, and the bulk-boundary correspondence indicating the robust boundary gapless states. Our group are interested in the theoretical analyze of novel topological states and the numerical calculation of topological materials, including topological semimetals, topological insulators and topological superconductors. In cooperation with experimental groups, we are also working on the experimental realization and detecting of those topological phases.
