Abstract

fetched live from OpenAlex

Point-contact spectroscopy was performed on single crystals of the heavy-fermion superconductor ${\mathrm{C}\mathrm{e}\mathrm{C}\mathrm{o}\mathrm{I}\mathrm{n}}_{5}$ between 150 mK and 2.5 K. A pulsed measurement technique ensured minimal Joule heating over a wide voltage range. The spectra show Andreev-reflection characteristics with multiple structures which depend on junction impedance. Spectral analysis using the generalized Blonder-Tinkham-Klapwijk formalism for $d$-wave pairing revealed two coexisting order parameter components with amplitudes ${\ensuremath{\Delta}}_{1}=0.95\ifmmode\pm\else\textpm\fi{}0.15\text{ }\text{ }\mathrm{m}\mathrm{e}\mathrm{V}$ and ${\ensuremath{\Delta}}_{2}=2.4\ifmmode\pm\else\textpm\fi{}0.3\text{ }\text{ }\mathrm{m}\mathrm{e}\mathrm{V}$, which evolve differently with temperature. Our observations indicate a highly unconventional pairing mechanism, possibly involving multiple bands.

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.
