Over the past decade, the field of topological states has boosted frontline research in condensed matter physics. It is witnessed that the prediction and discovery of topological materials have stimulated the rapid development of this field. In this talk, I will overview the general concepts of topological states. In combination with computational methods, chemistry insights are found to be rather helpful to discover topological materials, to realize the beautiful concepts and phenomena in physics. For example, the topological Weyl fermions were recently discovered in realistic materials with topological Fermi arcs on the surface and exotic transport phenomena in the bulk.
