Abstract

The stillness of electrons Anderson localization is one of the most interesting phenomena in solid-state physics: it predicts that an electron is immobilized when placed in a disordered lattice. Developed by Phillip Anderson in 1958 to explain how crystals stop conducting and become insulators (answer, when the density of defects in them increases), the model has been used for decades to account for electronic properties of solid-state structures. Yet true Anderson localization effects have not been observed in atomic crystals, as they tend to deviate from the model picture of a periodic potential with fluctuations frozen in time. Now new work carried out at the Haifa Technion confirms localization effects in a true Anderson lattice of a perturbed periodic potential, by using a photonic lattice on which random fluctuations are imposed. These findings raise intriguing questions about the fundamental nature of the interplay between disorder and nonlinearity.
