Evidence of phonon Anderson localization on the thermal properties of disordered atomic systems

Localization is a well-known wave phenomenon that significantly impedes transport, as uncovered by pioneering work of Anderson. The localization thermal phonons based on the phonon nature widely represented in disordered atomic systems. Compared with electron and photon localization, observations are much rarer, owning to broadband transport. In this Perspective, we summarize experimental theoretical evidences Anderson systems from aspects vibrational spectroscopy, conductivity measurement, transmission, packet, participation ratio, energy distribution.
