Diffusion of electrons in two dimensions in arbitrarily strong magnetic fields

Abstract

We show that results of a previous calculation by the present authors of the logarithmic corrections to the conductivity tensor of a two-dimensional interacting electronic system, in a random array of pointlike impurities, hold true irrespective of the strength of the applied magnetic field. The results are independent of the detailed form of the electronic self-energy calculated in the self-consistent Born approximation.
