Anderson localization of two-dimensional Dirac fermions: a perturbative approach

Abstract
- Anderson localization is studied for two-dimensional Dirac fermions in the presence of strong random scattering. Averaging with respect to the latter leads to a graphical representation of the correlation function with entangled random walks and three-vertices which connect three different types of propagators. This approach indicates Anderson localization along a semi-infinite line, where the localization length is inversely proportional to the scattering rate.<br />Comment: 8 pages, 2 figures
