Dirac vs. Weyl in topological insulators: Adler-Bell-Jackiw anomaly in transport phenomena

Heon-Jung Kim, Ki-Seok Kim, J. F. Wang +6

Dirac metals (gapless semi-conductors) are believed to turn into Weyl metals when perturbations, which break either time reversal symmetry or inversion symmetry, are employed. Howe…
