Vibrational excitations in systems with correlated disorder
W. Schirmacher, B. Schmid, C. Tomaras +4
We investigate a -dimensional model ( = 2,3) for sound waves in a disordered environment, in which the local fluctuations of the elastic modulus are spatially correlated with…

Elastic constant dishomogeneity and dependence of the broadening of the dynamical structure factor in disordered systems
M. Montagna, G. Ruocco, G. Viliani +5
We propose an explanation for the quadratic dependence on the momentum , of the broadening of the acoustic excitation peak recently found in the study of the dynamic structure f…
