Topological phases in condensed matter

Electrons in a crystal form band structure, and their wavefunctions in momentum space have topological structure characterized by Berry curvature. This curvature leads to various Hall effects, and to various topological phases. In my talk we give an overview of physical phenomena from Berry curvature in momentum space. Particularly, we focus on topological semimetals, whose band structures are gov-erned by profound interplay between topology and symmetry. We then discuss realization of such phenomena, not only in electronic systems but also in other particles.
