It has been recently shown that one can understand the Prigogine-Defay ratio at the glass transition in terms of freezing into one of the many inherent states of the undercooled liquid. In the present paper, the treatment is extended to the…
The glass transition can simply be viewed as the point at which the viscosity of a structurally disordered liquid reaches 10^{13} Poise [1]. This definition is operational but it sidesteps fundamental controversies about the glass: Is the…
The evolution of the aging process of glassy materials quenched from temperatures above their glass transition temperature $T_g$, when plotting the relaxed enthalpy versus the decrease in volume, leads to a slope comparable to the…
