Description
I describe the determination of the abelian axial anomaly in the so-called multi-Weyl and triple-point crossing semimetals. Three different computation methods are considered: the perturbative quantum field theory procedure which is based on the evaluation of the one-loop Feynman diagrams, the Nielsen-Ninomiya method and the Atiyah-Singer index argument.
