摘要：

I accurately solve the Schrodinger equation in magnetic field B for a random set of 2D point potentials. When B = 0, they yield a mobility edge. When B not-equal 0, all states are localized below a certain energy E(c)(B). Above E(c)(B), they are extended at the Landau energies. At other energies the localization length is a discontinuous function of B at every rational value of eBd2/ch, where d is an average interpotential distance.
