Abstract
For three decades, the superconducting order parameter symmetry in Sr${}_{2}$RuO${}_{4}$ has remained elusive. In most superconductors this symmetry manifests in the structure of the magnetic vortex lattice induced by applying a magnetic field. The minimum field of the vortex lattice is typically located at the center of a triangular or square arrangement of vortices. The authors report here on an unusual situation for Sr${}_{2}$RuO${}_{4}$, where the minimum field appears to be between midway between nearest-neighbor vortices in a square lattice. This finding introduces another constraint on possible superconducting order parameters.

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.
