We consider Dirac quasiparticles, as realized with cold atoms loaded in a honeycomb lattice or in a π -flux square lattice, in the presence of a weak correlated disorder such that the disorder fluctuations do not couple the two Dirac points of the lattices. We numerically and theoretically investiga...
