"Dirac fermions in a power-law correlated random vector potential"


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 compute the low-energy 
density of states and discuss a possible (pre)localization of the 
entire single particle spectrum.
