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 … Visa mer In condensed matter physics, Anderson localization (also known as strong localization) is the absence of diffusion of waves in a disordered medium. This phenomenon is named after the American physicist Visa mer In the original Anderson tight-binding model, the evolution of the wave function ψ on the d-dimensional lattice Z is given by the Schrödinger equation Visa mer Standard diffusion has no localization property, being in disagreement with quantum predictions. However, it turns out that it is based on approximation of the principle of maximum entropy Visa mer • Fifty years of Anderson localization, Ad Lagendijk, Bart van Tiggelen, and Diederik S.
