Off-equilibrium fluctuation dissipation relation in binary mixtures
Giorgio Parisi
Abstract
In this note we present numerical simulations of binary mixtures. We study the diffusion of particles and the response to an external driving force. We find evidence for the validity of the Cugliandolo Kurchan off-equilibrium fluctuation dissipation relation. The results are in agreement with the predictions of one step replica symmetry breaking and the dependance of the breakpoint parameter on the temperature coincide with that found in simple generalized spin glass models.
