Abstract

fetched live from OpenAlex

Two high-pressure insulating phases of lithium were predicted using random search and evolutionary algorithm methods with first-principles electronic structure calculations. It is shown that lithium will transform from the metallic cubic cI16 phase to an insulating monoclinic C2 structure at 74 GPa. The C2 structure is the most stable phase up to 91 GPa, where it transforms to a second insulating orthorhombic Aba2 structure. The C2 and Aba2 structures are the first theoretical models explicitly showing the band gap opening in compressed lithium. The theoretical findings are supported by recent experimental evidence from electrical resistance and x-ray diffraction measurements.

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.
