摘要：

We study an electron in a two-dimensional system of random point scatterers placed on the sites of a regular square lattice subject to a perpendicular magnetic field B. When the energy equals the Landau energy epsilon(n)(B) (n = 0,1,...) above a certain magnetic field B(n), (which corresponds to the presence of n + 1 flux quanta PHI0 = hc/e per an elementary square) we find analytically disorder-independent extended eigenstates.
