Abstract
The electronic properties, lattice dynamics, and electron-phonon coupling of boron with $\ensuremath{\alpha}\text{\ensuremath{-}}\mathrm{Ga}$ structure are studied as a function of pressure by ab initio calculations. It is found that $\ensuremath{\alpha}\text{\ensuremath{-}}\mathrm{Ga}$ boron is dynamically stable at high pressure. Electron-phonon calculations suggest that $\ensuremath{\alpha}\text{\ensuremath{-}}\mathrm{Ga}$ boron is superconducting with strong anisotropy. Analysis of the phonon linewidths shows that the in-plane $\ensuremath{\sigma}$-bonding states couple strongly with the $y\text{\ensuremath{-}}z$ in-plane vibrations, contributing mainly to the electron-phonon coupling. The theoretical results suggest that the $\ensuremath{\alpha}\text{\ensuremath{-}}\mathrm{Ga}$ structure might be a good candidate for the high-pressure metallic phase of boron.

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; both teacher heads agree on what is shown here.
