Tails of the Density of States in a Random Magnetic Field
arXiv:cond-mat/0412517 · doi:10.1103/PhysRevB.71.193302
Abstract
We study the tails of the density of states of fermions subject to a random magnetic field with non-zero mean with the Optimum Fluctuation Method (OFM). Closer to the centres of the Landau levels, the density of states is found to be Gaussian, whereas the energy dependence is non-analytic near the lower bound of the spectrum.
