Vibrational Spectrum of Topologically Disordered Systems
Vibrational Spectrum of Topologically Disordered Systems
The topological nature of the disorder of glasses and supercooled liquids strongly affects their high-frequency dynamics. In order to understand its main features, we analytically studied a simple topologically disordered model, where the particles oscillate around randomly distributed centers, interacting through a generic pair potential. We present results of a …
