| Summary: | We study localization properties of two-dimensional Dirac fermions subject to a powerlaw-correlated random vector potential describing, e.g., the effect of 'ripples' in a free standing graphene. By using a variety of techniques (low-order perturbation theory, self-consistent Born approximation, replicas, and supersymmetry) we compute the low-energy density of states and discuss a possible (pre)localization of the entire single-particle spectrum. |
