Abstract

An argument is presented to explain the observed increase in the density of states at low energy of a hamiltonian describing a charged particle with spin 1 2 and with a g-factor = 2 in the presence of a random magnetic field in two dimensions. This effect is equivalent to chiral symmetry breaking in the quenched massless euclidean Schwinger model.
