Exact Density of States in a System of Disordered Two Dimensional Dirac Fermions in the Unitarity Limit: The d-wave Superconductor
Catherine Pepin, Patrick A. Lee
In this paper we present a method to compute the exact density of states induced by non magnetic impurities in a system of two dimensional Dirac fermions in the unitarity limit…
