On the replica scenario for the glass transition

Abstract

In this letter we study a lattice gas system that undergoes a glassy transition. When we approach the glass transition we find both a divergence of a point to set correlation length and the vanishing of the thermodynamic potential. These findings are similar to the predictions coming from mean-field (replica) theory, but they differ from these predictions in some details: they underline the need of a better theoretical understanding of the glassy transition.
