Abstract

The non-equilibrium self-consistent generalized Langevin equation (NE-SCGLE) theory of irreversible processes in liquids has been proposed as a theoretical framework capable of predicting the age- and preparation-dependent properties of highly ubiquitous non-equilibrium amorphous solids, such as like glasses and gels. By this formalism, we discuss the main kinetic features of the irreversible relaxation of simple liquids involved in the arrested spinodal decomposition of suddenly and deeply quenched. At some lower temperature we identify, by means of a latency time within which particles retain a finite apparently stationary mobility, the crossover from full phase separation to arrested spinodal decomposition which leads to recognize the onset of gelation.
