Weak localization of two-dimensional Dirac fermions beyond the diffusion regime

We develop a microscopic theory of the weak localization of two-dimensional massless Dirac fermions, which is valid in the whole range of classically weak magnetic fields. The theory is applied to calculate the magnetoresistance caused by the weak localization in graphene and topological insulators.
