If you have a question about this talk, please contact Vincent Boyer. Note unusual time Anderson localization occurs always in less than three dimensions in presence of white noise disorder. But when introducing correlations, as like is the case of the Random Dimer Model, a subset of eigenstates can be delocalized. It is a case of short-range correlation, here neighboring sites of identical site energy are assigned to appear as pairs, thus forming a dimer (1). This presentation is about the preparations towards an experimental study of the localization-delocalization transition in a one dimensional Random Dimer Model by emulating the tight-binding model in a microwave cavity with two types of dielectric scatterers. Recently the Anderson tight-binding model was successfully emulated with this experimental setup in order to investigate transport properties of Graphene like structures (2,3). - D.Dunlap & al. “Absence of localization in a Random Dimer Model”
