Among the unusual transport properties predicted for disordered materials is the Anderson localization phenomenon. This is a disorder-induced phase transition in the electron-transport behaviour from the classical diffusion regime, in which the well-known Ohm's law holds, to a localized state in which the material behaves as an insulator. The effect finds its origin in the interference of electrons that have undergone multiple scattering by defects in the solid. A similar phenomenon is… 

Transport and Anderson localization in disordered two-dimensional photonic lattices

TLDR
The experimental observation of Anderson localization in a perturbed periodic potential is reported: the transverse localization of light caused by random fluctuations on a two-dimensional photonic lattice, demonstrating how ballistic transport becomes diffusive in the presence of disorder, and that crossover to Anderson localization occurs at a higher level of disorder.

Light scattering in disordered and nonreciprocal media

The statistical properties of light emission and transport in disordered media have been a matter of intense research since the foundation of the electromagnetic theory. Questions such as Anderson

Anderson localization of a non-interacting Bose–Einstein condensate

TLDR
This work uses a non-interacting Bose–Einstein condensate to study Anderson localization of waves in disordered media and describes the crossover, finding that the critical disorder strength scales with the tunnelling energy of the atoms in the lattice.

Observation of the critical regime near Anderson localization of light.

TLDR
Time resolved measurements of light transport through strongly scattering samples with kl* values as low as 2.5 constitute an experimental realization of the critical regime in the approach to Anderson localization.

Direct observation of Anderson localization of matter waves in a controlled disorder

TLDR
This work directly image the atomic density profiles as a function of time, and finds that weak disorder can stop the expansion and lead to the formation of a stationary, exponentially localized wavefunction—a direct signature of Anderson localization.

Light transport behaviours in quasi-1D disordered waveguides composed of random photonic lattices

We present a numerical study on the light transport properties which are modulated by the disorder strength in quasi-one-dimensional disordered waveguide which consists of periodically arranged

Probing Anderson localization of light by weak non-linear effects

Breakdown of wave transport due to strong disorder is a universal phenomenon known as Anderson localization (AL). It occurs because of the macroscopic population of reciprocal multiple scattering

Anderson localization of matter waves

The transport of quantum particles in non ideal material media (eg the conduction of electrons in an imperfect crystal) is strongly affected by scattering from impurities of the medium. Even for a

Quantum Transport in Presence of Disorder

Waves may fail to propagate in random media. First predicted for quantum particles in the presence of a disordered potential, Anderson localization has been observed also in classical acoustics,

Transition from light diffusion to localization in three-dimensional amorphous dielectric networks near the band edge

TLDR
It is shown that the transition to localization at the mobility edge can be described using the self-consistent theory of localization based on the concept of a position-dependent diffusion coefficient, and that transport sets off diffusive but, with increasing slab thickness, crosses over gradually to a faster decay, signaling localization.

Localization of photons in disordered systems

Abstract We discuss weak and strong localization of photons in disordered systems. In particular, we review the recent theoretical and experimental developments relating to the following phenomena:

Experimental evidence for recurrent multiple scattering events of light in disordered media.

TLDR
Coherent backscattering manifests itself in the form of an enhancement of the intensity in the back direction for the light scattered from a disordered sample, which originates from constructive interference between multiply scattered amplitudes and their time reversed counterparts.

TLDR

TLDR
It is shown that the effect of internal reflection due to index mismatch can be quantitatively accounted for with a single parameter by incorporating a reflection coefficient into the boundary condition for the diffusive light.

Absence of Diffusion in Certain Random Lattices

This paper presents a simple model for such processes as spin diffusion or conduction in the "impurity band." These processes involve transport in a lattice which is in some sense random, and in them
