摘 要:Chiral anomaly and the novel quantum phenomena it induces have been widely studied for Dirac and Weyl *** most typical cases,the Lorentz covariance is assumed and thus the linear dispersion relations are ***,in realistic materials,such as Dirac and Weyl semimetals,the nonlinear dispersion relations appear *** develop a kinetic framework to study the chiral anomaly for Weyl fermions with nonlinear dispersions using the methods of Wigner function and semi-classical equations of *** this framework,the chiral anomaly is sourced by Berry monopoles in momentum space and could be enhanced or suppressed due to the windings around the Berry *** results can help understand the chiral anomaly-induced transport phenomena in non-relativistic systems.
