“…where t(0), t(1), and t(t) are the initial peak position, the final equilibrium peak position, and the peak position at the heat-treatment time, t, respectively, of the germania glass structural band [10]. The relaxation time, s, for germania glass samples initially at a fictive temperature of 550°C was 17 min while that for germania glass samples with an initial fictive temperature of 500°C was 33 min.…”

“…In traditional glass science the concept of "fictive temperature" is used as a structural characteristic that by definition gives the temperature at which the structure would be in equilibrium [54][55][56][57][58][59]. For any aging experiment, in glass science one assumes that the fictive temperature adjusts itself monotonically from the initial temperature to the final temperature.…”

This paper summarizes the properties of strongly correlating liquids, i.e., liquids with strong correlations between virial and potential energy equilibrium fluctuations at constant volume. We proceed to focus on the experimental predictions for strongly correlating glass-forming liquids. These predictions include i) density scaling, ii) isochronal superposition, iii) that there is a single function from which all frequency-dependent viscoelastic response functions may be calculated, iv) that strongly correlating liquids are approximately single-parameter liquids with close to unity PrigogineDefay ratio, and v) that the fictive temperature initially decreases for an isobaric temperature up jump. The "isomorph filter", which allows one to test for universality of theories for the nonArrhenius temperature dependence of the relaxation time, is also briefly discussed.

“…Therefore, T f depends on the type of macroscopic property measured in the system (see e.g. [13]). Thus if we measure the configurational enthalpy H , volume V , etc., the fictive temperature determined will depend on the corresponding property.…”
