Glass-Freeze Analysis Protocol v0: CPA Rate Comparison Debra S. Gavant November 2025 Purpose This preregistration establishes the analytical plan and provenance for the comparative test of the CPA Freeze model, derived from Dynamic Present Theory (DPΦ), against standard kinetic descriptions of glass transition behavior. The intent is to evaluate whether informational constraint predicts the observed slowdown of dynamics in supercooled liquids more accurately than classical models. Scope and Authorship Comparative data analysis is being performed by Dr. Christian E. Precker, an independent physicist who is contributing to the implementation and validation of the CPA Freeze model using canonical glass-forming datasets provided by Dr. Samuel Frueh. All conceptual framing and model formulation originate from the author, with results to be archived under this preregistration. Model Comparison Three laws will be evaluated: 1. Arrhenius: τ(T)=τ0exp(Ea/kBT) 2. Vogel–Fulcher–Tammann (VFT): τ(T) = τ0exp[A/(T−T0)] 3. CPA Freeze: τ(T)=τ0exp[κ(Tg−T)] Performance metrics will include R2, reduced χ2, RMSE, AIC, and BIC. Model residuals will be inspected for systematic deviations. Planned Deliverables •Implementation of the λ-weighted constraint term within CPA Freeze code. •Comparative fit tables and plots for Arrhenius, VFT, and CPA models. •Summary report documenting parameter stability and fit quality. Status Data analysis in progress (October-November 2025). Final results will be archived separately under a new Zenodo DOI referencing this preregistration. 1
