Extended state floating up in a lattice model: Bona fide levitation fingerprints, irrespective of the correlation length
Ana L. C. Pereira, P. A. Schulz
Abstract
The evolution of extended states with magnetic field and disorder intensities is investigated for 2D lattice models. The floating-up picture is revealed when the shift of the extended state, relative to the density of states, is properly taken into account, either for white-noise or correlated disorder.
