Isotherms for the liquid-gas phase transition in silicon from NPT Monte Carlo simulations
Bibliographic record
Abstract
Isotherms for the liquid-gas phase transition in silicon have been calculated using isothermal-isobaric (NPT) Monte Carlo simulations with atom-atom interactions described by the Stillinger-Weber potential. In order to permit high-performance Monte Carlo calculations, a procedure has been developed to compute efficiently changes in the potential energy resulting from one-atom moves; the method is applicable to the Stillinger-Weber potential and other potentials with separable three-body terms. For Stillinger-Weber silicon, the critical temperature, pressure and density have been found to be $7925\ifmmode\pm\else\textpm\fi{}250\mathrm{K},$ $185\ifmmode\pm\else\textpm\fi{}40\mathrm{MPa},$ and $760\ifmmode\pm\else\textpm\fi{}500{\mathrm{k}\mathrm{g}/\mathrm{m}}^{3},$ respectively. From the calculated isotherms, the spinodal line for the liquid-gas phase transition has been estimated.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
