Abstract

As discussed in detail in Chap. 5, vibrational excitations in fractal networks behave in a different manner from those in conventional disordered systems. These excitations called fractons are characterized by the spectral dimension d s. However, all the results on fractons presented in Chap. 5 are deduced from the scaling assumption (5.8). In order to confirm the results derived from the scaling arguments and clarify the nature of fractons, investigation by computer simulations is crucial. This has become possible recently due to a sharp increase in available computer power together with the development of new algorithms suitable for large-scale computations. These have been a great success in quantitatively describing the dynamics of complex systems.
