Semiclassical Boltzmann transport theory for multi-Weyl semimetals

Multi-Weyl semimetals are a new type of Weyl semimetals which have linear dispersion along one symmetry direction and anisotropic non-linear dispersion along the remaining two directions with a topological charge larger than one. Using the semiclassical Boltzmann transport theory fully incorporating the anisotropy of the system, we calculate DC conductivity as a function of density and temperature, and obtain its characteristic density and temperature dependence derived from the topological band structure of the system.
