The disordered single Weyl cone

We numerically study a single Weyl cone in the presence of short-range disorder. By representing the Hamiltonian in a ``mixed’’ way between real and momentum space we are able to invoke fast Fourier transforms to take advantage of efficient numerical routines (such as Lanczos and the kernel polynomial method) that rely on sparse matrix-vector multiplications. As a result, we can reach sufficiently large system sizes that are comparable to lattice model simulations. We study the distinctions that arise between lattice models that contain band curvature and multiple Weyl nodes that have internode scattering with the case of a single Weyl node with a perfectly linear dispersion. We will report results on the nature of rare regions and the density of states as a function of the strength of disorder as well as compare and contrast single node and multinode situations.
