Graphene topological
WebProminent examples of Dirac matter are Graphene, topological insulators, Dirac semimetals, Weyl semimetals, various high-temperature superconductors with -wave pairing and liquid Helium-3. The effective theory of such systems is classified by a specific choice of the Dirac mass , the Dirac velocity, the Dirac matrices and the space-time curvature .
