Abstract

fetched live from OpenAlex

Thermal conductivity of ${\mathrm{Sr}}_{3}{\mathrm{Ru}}_{2}{\mathrm{O}}_{7}$ was measured down to 40 mK and at magnetic fields through the quantum critical end point at ${H}_{c}=7.85\text{ }\text{ }\mathrm{T}$. A peak in the electrical resistivity as a function of the field was mimicked by the thermal resistivity. In the limit as $T\ensuremath{\rightarrow}0\text{ }\text{ }\mathrm{K}$, we find that the Wiedemann-Franz law is satisfied to within 5% at all fields, implying that there is no breakdown of the electron despite the destruction of the Fermi liquid state at quantum criticality. A significant change in disorder [from ${\ensuremath{\rho}}_{0}(H=0\text{ }\text{ }\mathrm{T})=2.1$ to $0.5\text{ }\text{ }\ensuremath{\mu}\ensuremath{\Omega}\text{ }\mathrm{cm}$] does not influence our conclusions. At finite temperatures, the temperature dependence of the Lorenz number is consistent with ferromagnetic fluctuations causing the non-Fermi liquid behavior as one would expect at a metamagnetic quantum critical end point.

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.
