Abstract

fetched live from OpenAlex

High-resolution, inelastic neutron scattering measurements on ${\mathrm{S}\mathrm{r}\mathrm{C}\mathrm{u}}_{2}({\mathrm{B}\mathrm{O}}_{3}{)}_{2}$, a realization of the Shastry-Sutherland model for two-dimensional Heisenberg antiferromagnets, reveal the dispersion of the three single triplet excitations continuously across the $(H,0)$ direction within its tetragonal basal plane. These measurements also show distinct $\mathbf{Q}$ dependencies for the single and multiple triplet excitations, and that these excitations are largely dispersionless perpendicular to this plane. The temperature dependence of the intensities of these excitations is well described as the complement of the dc susceptibility of ${\mathrm{S}\mathrm{r}\mathrm{C}\mathrm{u}}_{2}({\mathrm{B}\mathrm{O}}_{3}{)}_{2}$.

Full frame distilled prediction

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.
