Abstract

Various experimental manifestations of an average order in amorphous solids and glasses are discussed. The localization of phonons in microscopic regions bounded by the average-order radius leads to a local heating of these regions in an interaction of light with the matter. The concept of an effective temperature of microscopic regions with nonequilibrium local phonons is introduced, and its value is estimated. These results are used to construct a model for photostructural conversions in chalcogenide glasses. Other physical phenomena due to a local heating are discussed.
