The disordered systems are of fractal structures. Alexander and Orbach showed that the vibrational density of states for fractal nets follow. the universal law:D(omega) similar to omega(2-:) where d is the spectral (fracton) dimensionality;d=4/3 for any Euclidean dimension d. The excitations belongi...
