Seminar on Disorder and strong electron correlations: "Dirac fermions in a power-law correlated random vector potential"
ICTP (Main Building Seminar Room)
(University of North Carolina, Chapel Hill)
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.
