Dirac fermions in a power-law-correlated random vector potential
arXiv:0705.4105 · doi:10.1209/0295-5075/82/57008
Abstract
We study localization properties of two-dimensional Dirac fermions subject to a power-law-correlated random vector potential describing, e.g., the effect of "ripples" in graphene. By using a variety of techniques (low-order perturbation theory, self-consistent Born approximation, replicas, and supersymmetry) we make a case for a possible complete localization of all the electronic states and compute the density of states.
