Multiple scattering is a universal phenomenon occurring in almost every branch of physics. Everyday around us we see examples of multiple scattering of light in random media (clouds, white paper, refined sugar).
Up to a few years ago multiple scattering, giving rise to diffusive transport, was considered to be a dull theme. This picture changed radically after the discovery that concept of Anderson localization not only applies to quantum mechanical electrons but also to classical waves as light and sound. Anderson localization is a wave-interference effect induced by disorder. In principle it could be observed in different systems, varying from cold gasses to semi-conductor powders.
We will present our observations of localization of light in various systems.
