 The dynamical structure factor of topologically disordered systems

A computation of the dynamical structure factor of topologically disordered systems, where the disorder is decribed by means of euclidean random matrices, is shown. Among the others, supercooled liquids belong to that class of systems and this computation describe correctly their relevant spectral features, namely the high frequency sound and the so-called 'Boson peak'.
