Description

A supersymmetric formalism is used to rederive a recent beautiful result of Wegner concerning the density of states of an electron gas in the presence of a strong magnetic field and impurities. The derivation is simple and applicable to any (local) distribution of scatterers. Explicit formulae are given in two dimensions. A Poisson distribution of scatterers leads to an interesting condensation phenomenon when the magnetic field is increased. (orig.)
