Query: Surface Green's functions and boundary modes using impurities: Weyl
  semimetals and topological insulators   In this work we provide a new direct and non-numerical technique to obtain
the surface Green's functions for three-dimensional systems. This technique is
based on the ideas presented in Phys. Rev. B 100, 081106(R), in which we start
with an infinite system and model the boundary using a plane-like
infinite-amplitude potential. Such a configuration can be solved exactly using
the T-matrix formalism. We apply our method to calculate the surface Green's
function and the corresponding Fermi-arc states for Weyl semimetals. We also
apply the technique to systems of lower dimensions, such as Kane-Mele and Chern
insulator models, to provide a more efficient and non-numerical method to
describe the formation of edge states.
