Conductance characteristics between a normal metal and a two-band superconductor carrying a supercurrent
Bibliographic record
Abstract
The conductance is calculated for a point contact junction between a normal metal and a two-band superconductor with a supercurrent applied parallel to the junction interface. Predictions are made for the case of $\mathrm{Mg}{\mathrm{B}}_{2}$, which would allow for the determination of the two energy scales and interband coupling. In addition, the generic features of two-band superconductivity in this configuration are studied and contrasted with the one-band case. It is found that two peaks are possible in the zero bias conductance as a function of superfluid momentum ${q}_{s}$ for the case of two-band superconductivity, whereas only one could occur in the one-band case. We analyze the case of highly decoupled bands to examine further the potential signatures of interband coupling.

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; a candidate call from one teacher head, not a consensus.
