We study the tails of the density of states of particles subject to a random magnetic field with nonzero mean with the optimum fluctuation method. Closer to the centers of the Landau levels, the density of states is found to be Gaussian, whereas the energy dependence is nonanalytic near the lower edge of the spectrum.

Abstract
We study the tails of the density of states of particles subject to a random magnetic field with nonzero mean with the optimum fluctuation method. Closer to the centers of the Landau levels, the density of states is found to be Gaussian, whereas the energy dependence is nonanalytic near the lower edge of the spectrum.File allegati a questo prodotto
