Non-centrosymmetric superconductor La3Bi4Pt3
Bibliographic record
Abstract
Recently, we have discovered that the metallic La3Bi4Pt3 (Y3Au3Sb4 structure) becomes superconducting below a transition temperature Tc of about 1.4K. Our interest in the superconducting phase of La3Bi4Pt3 stems from the fact that it lacks a center of inversion, which may lead to unconventional su- perconductivity, including nodes in the superconducting gap function, even if the pair wave function exhibits the full spatial symmetry of the crystal. Compared to other non-centrosymmetric magnetic compounds in which superconductivity has recently been discovered, like CePt3Si, UIr, CeRhSi3 (under pressure), the nature of the superconducting state in La3Bi4Pt3 is not complicated by strong electron correlations nor the coexistence of magnetism. This makes it a good model system to study superconductivity without inversion symmetry. In our presentation we will focus on the first basic characterization of our La3Bi4Pt3 single crystals (X-ray, specifc heat, resistivity, penetration depth, etc.).

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.
