Query: Disordered double Weyl node: Comparison of transport and
  density-of-states calculations   Double Weyl nodes are topologically protected band crossing points which
carry chiral charge $\pm2$. They are stabilized by $C_{4}$ point group symmetry
and are predicted to occur in $\mathrm{SrSi_{2}}$ or $\mathrm{HgCr_{2}Se_{4}}$.
We study their stability and physical properties in the presence of a disorder
potential. We investigate the density of states and the quantum transport
properties at the nodal point. We find that, in contrast to their counterparts
with unit chiral charge, double Weyl nodes are unstable to any finite amount of
disorder and give rise to a diffusive phase, in agreement with predictions of
Goswami and Nevidomskyy [Phys. Rev. B 92, 214504 (2015)] and Bera, Sau, and Roy
[Phys. Rev. B 93, 201302(R) (2016)]. However, for finite system sizes a
crossover between pseudodiffusive and diffusive quantum transport can be
observed.
