Abstract

fetched live from OpenAlex

The validity of the commonly used quantum corrections for mapping a classically predicted thermal conductivity onto a corresponding quantum value are assessed by self-consistently predicting the classical and quantum thermal conductivities of a crystalline silicon system via lattice-dynamics calculations. Applying the quantum corrections to the classical predictions, with or without the zero-point energy, does not bring them into better agreement with the quantum predictions compared to the uncorrected classical values above temperatures of 200 K. By examining the mode dependence of the phonon properties, we demonstrate that thermal conductivity cannot be quantum corrected on a system level. We explore the source of the differences in the quantum and classical phonon relaxation times on a mode-by-mode basis.

Teacher imitation

Not 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.
