Moment-Preserving Theory of Vibrational Dynamics of Topologically Disordered Systems

Moment-Preserving Theory of Vibrational Dynamics of Topologically Disordered Systems

We investigate a class of simple mass-spring models for the vibrational dynamics of topologically disordered solids. The dynamical matrix of these systems corresponds to the Euclidean-Random-Matrix (ERM) scheme. We show that the self-consistent ERM approximation introduced by Ganter and Schirmacher...
