Query: Universality, exponents and anomaly cancellation in disordered Dirac
  fermions   Disordered 2D chiral fermions provide an effective description of several
materials including graphene and topological insulators. While previous
analysis considered delta correlated disorder and no ultraviolet cut-offs, we
consider here the effect of short range correlated disorder and the presence of
a momentum cut-off, providing a more realistic description of condensed matter
models. We show that the density of states is anomalous with a critical
exponent function of the disorder and that conductivity is universal only when
the ultraviolet cut-off is removed, as consequence of the supersymmetric
cancellation of the anomalies.
