Aging in simple liquids: a numerical study

Francesco Sciortino, Piero Tartaglia
2001 Journal of Physics: Condensed Matter  
We discuss the phenomenon of physical aging in a well studied atomic model liquid, a binary mixture of particles interacting with Lennard-Jones potentials. We put emphasis on the different dynamical behaviours of the model as well as on the relations between the experimental and numerical timescales. The physics of aging is discussed within a well characterized thermodynamic framework, based on properties of the model potential energy surface.
