Dirac Materials
During the last decade there has been an explosion of work on the so-called Dirac materials: solid crystalline materials with the electronic structure near the Fermi surface resembling the energy dispersion of relativistic Dirac fermions. These include graphene, topological insulators and superconductors, and Weyl semimetals. Such materials are interesting both as a potential source of new technological applications and from the fundamental physics standpoint. This is because their physics is to a large extent determined by topological properties of the electronic structure, which represents a departure from the standard paradigm of symmetry (which is a geometrical rather than topological concept) playing a fundamental role in physics. I will present a broad overview of some of the recent work on Dirac materials, including my own work on Weyl semimetals, emphasizing the role of topology in their observable physical properties.
