Abstract
The ratio of the far-infrared reflectance of ${\mathrm{Sr}}_{2}\mathrm{Ru}{\mathrm{O}}_{4}$ in the superconducting state ${R}_{S}$ to that in the normal state ${R}_{N}$ has been measured. For light polarized within the $ab$ plane, the superconducting state reflectance is enhanced over that of the normal state below $\ensuremath{\approx}20\phantom{\rule{0.3em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}1}$, with the thermal reflectance ratio ${R}_{S}∕{R}_{N}$ peaking near $9\phantom{\rule{0.3em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}1}$. The energy at which the thermal reflectance peaks, and the magnitude of its enhancement are significantly larger than expected due to the formation of a BCS energy gap. The energy scale coincides with the superconducting energy gap of ${\mathrm{Sr}}_{2}\mathrm{Ru}{\mathrm{O}}_{4}$ determined via tunneling measurements.

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.
