  Multi-Weyl semimetals (m-WSMs) are a new type of Weyl semimetal that have
linear dispersion along one symmetry direction but anisotropic non-linear
dispersion along the two transverse directions with a topological charge larger
than one. Using the Boltzmann transport theory and fully incorporating the
anisotropy of the system, we study the DC conductivity as a function of carrier
density and temperature. We find that the characteristic density and
temperature dependence of the transport coefficients at the level of Boltzmann
theory are controlled by the topological charge of the multi-Weyl point and
distinguish m-WSMs from their linear Weyl counterparts.
