Extended state floating up in a lattice model: Bona fide levitation fingerprints, irrespective of the correlation length

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.
