WebLa localisation d'Anderson est un phénomène général qui s'applique au transport des ondes électromagnétiques 6, des ondes acoustiques 7, des ondes quantiques, des ondes de spin 8, etc. Elle a pu être observée avec des atomes ultrafoids 9, 10. Ce phénomène est à distinguer de la localisation faible 11, qui est le précurseur de l ... WebAlthough Anderson localization of noninteracting particles has been experimentally observed in a variety of systems, including light scattering from semiconductor powders in three-dimensional (3D) (), photonic lattices in 1D and 2D (), and cold atoms in 1D and 3D random (27–29) and quasirandom disorder, the interacting case has proven more elusive.

"WebThe transport of waves in pseudospin-1 systems exhibits many interesting phenomena, including super Klein tunneling, robust supercollimation, and unconventional Anderson localization. The transport properties of pseudospin-1 systems are distinct from their counterparts in pseudospin-1/2 systems, which will also be presented for comparison. " - Photonic anderson localization

Two reports of Anderson localization of light in 3D random media exist up to date (Wiersma et al., 1997 and Storzer et al., 2006; see Further Reading), even though absorption complicates interpretation of experimental results (Scheffold et al., 1999). Anderson localization can also be observed in a perturbed periodic potential where the transverse localization of light is caused by random fluctuations on a photonic lattice.
