Anomaly related transport of Weyl fermions for Weyl semi-metals

Understand

We present a field theoretical model of anomalous transport in Weyl semi-metals.

• We calculate the Chiral Magnetic and Chiral Vortical Effect in the electric, axial (valley) and energy current.
• Our findings coincide with the results of a recent analysis using kinetic theory in the bulk of the material.
• We point out that the kinetic currents have to be identified with the covariant currents in quantum field theory.
