Topological theory of gapless and gapped fermionic systems
Recently the discoveries of graphene, Weyl semi-metal and Dirac semi-metal are drawing more and more people’s attentions back to the topological characteristics of Fermi surfaces, which may be tracked back to the pair of Weyl points observed experimentally in the phase A of Helium three in 80s in th...
