Physicists localize 3-D matter waves for first time

Physicists have experimentally demonstrated for the first time how three-dimensional conduction is affected by the defects that plague materials. The researchers achieved complete Anderson localization of quantum matter waves in three dimensions. The team also measured the energy a particle needs to escape localization, known as the mobility edge. They found that as disorder increased, so did the mobility edge, meaning that materials with high concentrations of defects induce more localization.
