The chiral anomaly in Weyl semimetals is responsible for various
anomalous transport phenomena. In tunnel junctions between Weyl semimetals
with staggered Weyl node projections, the chiral anomaly leads to a
magnetic-field activated magnetotransport. In this talk, I discuss the
effect of interface disorder on the magnetotransport across such a tunnel
junction employing a semiclassical Boltzmann approach. Our results show
that, compared to conventional transport channels, the topological
connectivity of interface Fermi arcs ensures that anomalous
magnetotransport exhibits stronger robustness against disorder.
Additionally, interface disorder enhances magnetic breakdown, a quantum
tunneling effect, between the Fermi arcs.
