Strain-Glass Revisited

According to the most general interpretation, a glassy transition (transition to the glassy state) is a transition between the high temperature “liquid” state in which certain species are disordered due to thermal excitation. This disordered “liquid” state is an equilibrium state and a “glassy” state is the one in which the same species are in a “frozen” disorder, inherited from the high-temperature “liquid” state. This is a kinetically non-equilibrium state, when the equilibrium state cannot be reached due to a divergence of the relaxation time.
