Off-equilibrium dynamics of the frustrated Ising lattice gas

We study by means of Monte Carlo simulations the oft-equilibrium properties of a model glass, the: frustrated Ising lattice gas in three dimensions. W e have computed typical two times quantities, such as density-density autoc orrelations and the autocorrelation of internal degrees of freedom. We find an aging scenario particularly interesting in the case of the density auto correlations in real space that is very reminiscent of spin glass phenomeno logy. While this model captures the essential features of structural glass dynamics. its; analogy with spin glasses may make possible its complete des cription using the tools developed in spin glass theory.
