Abstract

fetched live from OpenAlex

Knowledge on the composition and structure of a material are essential to the understanding of the properties. Recent advances in structural prediction techniques from first-principles calculations have greatly enhanced the perspective on the large variety of new crystal types, particularly, under extreme conditions at high pressure and high temperature. The structural information helps to develop a new understanding on the change in chemical bonding in highly compressed solids. I will present the results and experience in the use of several structural prediction methods with examples drawn from recent studies on the outstanding problems in pressure-induced amorphization of SnI4, structural transformations, atomic dynamics and structural chemistry of simple elemental and molecular solids at high pressure and high temperature. Our results will highlight the successes, challenges and future development on the practical applications of these methods.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
