MULTIAFFINE SCALING IN ONE-DIMENSIONAL DISORDERED-SYSTEMS

The multiaffine analysis is used to study the internal structures of t he transmittance in three different cases: a homogeneous random chain in the mesoscopic regime, an inhomogeneous random chain and a random c hain in the presence of an external electric field. We find large fluc tuations of transmittance in all three different types of systems and these obey anisotropic multiaffine scaling. This method provides a uni fied description of transmittance fluctuations in very different syste ms.
