Anderson localization

Anderson localization traps waves in disordered media

Anderson localization refers to the phenomenon where waves, such as electromagnetic or acoustic waves, fail to diffuse in a disordered medium. This trapping effect occurs because disorder in the medium disrupts the coherent propagation of waves.

Example

In a semiconductor with impurities, Anderson localization can trap electron waves, preventing them from spreading out and contributing to electrical conductivity.

Understanding Anderson localization is crucial for developing materials with specific wave propagation properties, such as insulators or semiconductors with tailored electronic characteristics.
