| Abstract: | The dynamical susceptibility has been introduced to characterize the dynamical
heterogeneities in glass forming liquids. We have used it as a tool to
investigate the slow dynamics
of other disordered systems such as gels, granular media and spin glasses.
We review here the results obtained via numerical simulations of different
model systems. The comparative study of the behaviour of the dynamical
susceptibility sheds some light on the significant differences in the
complex slow dynamics of glasses, spin glasses, granular media,
irreversible gels, and colloidal gels. |
