Abstract

We predict a fundamental scaling law of Bloch oscillation in Weyl semimetals, which manifests that the transverse drift of quasiparticles accelerated bypassing a Weyl point exhibits asymptotically a linear log-log relation with respect to the minimal momentum measured from the Weyl point. This scaling relation is deeply connected to the topological monopole structure of Weyl points, thus being universal and providing a scheme to measure bulk topology of Weyl semimetals.
