Tunneling conductance for<i>d</i>-wave superconductors: Dependence on crystallographic orientation and Fermi surface
Bibliographic record
Abstract
The dependence of the $\mathrm{ab}$-plane differential conductance of a normal-metal-insulator-${d}_{{a}^{2}\ensuremath{-}{b}^{2}}$-wave superconductor junction on the superconductor crystal orientation and its Fermi surface is investigated using a two-dimensional square lattice model. In the tunneling limit, when the orientation is away from {100} and {110}, the study shows that there are features at other energies in addition to a zero-bias conductance peak and a shoulderlike feature at the maximum gap. These additional features are found to occur at either the energy gap of the state with the momentum normal to the surface or the gap of the state with the momentum on the edge of the surface-adapted Brillouin zone, or at both of the energy gaps, depending on the shape of the Fermi surface. These considerations show that, in principle, tunneling can be used to determine the energy gap at wave vectors other than those at which the gap is at a maximum.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
