  The phenomenon of nonlinear transport has attracted tremendous interest
within the condensed matter community. We present a theoretical framework for
nonlinear transport based on the nonequilibrium retarded Green's function, and
examine the impact of disorder on nonlinear magnetotransport in Weyl semimetals
(WSMs). It is demonstrated that bilinear magnetoconductivity can be induced in
disordered WSMs by several mechanisms, including impurity-induced tilting of
the Weyl cones, Lorentz-force-induced normal orbital magnetic moment, and
chiral anomaly arising from the Berry-curvature-induced anomalous orbital
magnetic moment. Additionally, we observe that the localization of Weyl
fermions by impurity scattering will lead to resonant dips in both the chiral
chemical potential and magnetoconductivity when the Fermi energy approaches the
impurity resonance states. Our findings offer a theoretical proposition for
modulating nonreciprocal transport in topological semimetals.
