          Abstract

          In this note we present numerical simulations of binary mixtures and we find indications for a thermodynamic transition to a glassy phase. We find that below the transition point the off equilibrium correlation functions and response functions seems to be asymptotically compatible with the relations that were originally derived Cugliandolo Kurchan for generalized spin glasses.

          Analytical Solution of the Off-Equilibrium Dynamics of a Long Range Spin-Glass Model

          We study the non-equilibrium relaxation of the spherical spin-glass model with p-spin interactions in the \(N \rightarrow \infty\) limit. We analytically solve the asymptotics of the magnetization and the correlation and response functions for long but finite times. Even in the thermodynamic limit the system exhibits `weak' (as well as `true') ergodicity breaking and aging effects. We determine a functional Parisi-like order parameter \(P_d(q)\) which plays a similar role for the dynamics to that played by the usual function for the statics.

            Numerical Evidence for Spontaneously Broken Replica Symmetry in 3D Spin Glasses

            By numerical simulations of the \(3d\) Ising spin glass we find evidence that spontaneous replica symmetry breaking theory and not the droplet model describes with good accuracy the equilibrium behavior of the system.
