Reply to “Comment on ‘Chiral gauge field and axial anomaly in a Weyl semimetal’ ”

Recently, in their Comment, Zhang et al. question our results of anomaly equations. In this Reply, we provide detailed derivation of anomaly equations from microscopic models and explain the reason why we respectfully disagree with the derivation and argument in the Comment.

The energy dispersion of Weyl semimetals is shown along the $k_z$ direction. Weyl fermions are located at $\pm K_0$ and the momentum regions I and II are labeled.
