Thermodynamics of binary mixture glasses

We compute the thermodynamic properties of the glass phase in a binary mixt ure of soft spheres. Our approach is a generalization to mixtures of the re plica strategy, recently proposed by Mezard and Parisi, providing a first p rinciple statistical mechanics computation of the thermodynamics of glasses . The method starts from the interatomic potentials, and translates the pro blem into the study of a molecular liquid. We compare our analytical predic tions to numerical simulations, focusing onto the values of the thermodynam ic transition temperature and the configurational entropy.
