Abstract

The possibility for carbon materials such as activated carbon fibers or graphite ribbons, to support edge-states could change drastically their magnetic properties. 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.
