Abstract
In high-purity ${\mathrm{YBa}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7}$, the (weak-field) thermal Hall conductivity ${\ensuremath{\kappa}}_{\mathrm{xy}}$ is observed to increase a thousand-fold between 90 and 30 K. The inferred quasiparticle lifetime $\ensuremath{\tau}$ increases a hundred-fold starting below 90 K, in disagreement with a recent photoemission experiment. We show that ${\ensuremath{\kappa}}_{\mathrm{xy}}$ exhibits a specific scaling behavior below $\ensuremath{\sim}30K$. This scaling may bear on the issue of whether Landau quantization of the quasiparticle states occurs.

How this classification was reachedexpand
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; both teacher heads agree on what is shown here.
