The dynamical properties of the site frustrated percolation model are investigated and compared with those of glass-forming liquids. When the density of the particles on the lattice becomes high enough, the dynamics of the model becomes very slow, due to geometrical constraints, and rearrangement on large scales is needed to allow relaxation. The autocorrelation functions, the specific volume for different cooling rates, and the mean-square displacement are evaluated and are found to exhibit glassy behavior.

Abstract
The dynamical properties of the site frustrated percolation model are investigated and compared with those of glass-forming liquids. When the density of the particles on the lattice becomes high enough, the dynamics of the model becomes very slow, due to geometrical constraints, and rearrangement on large scales is needed to allow relaxation. The autocorrelation functions, the specific volume for different cooling rates, and the mean-square displacement are evaluated and are found to exhibit glassy behavior.File in questo prodotto:
