The purpose of this work is to propose a novel way to identify the existence of those states by considering the behaviour of the static electric polarizability under a perpendicular magnetic field. The edge-sates are shown to induce a quadratic dependence on magnetic field detectable experimentally nowaday.5 pages, 2 eps figsCondensed Mattertext
