Pressure-induced reactions in minerals: a condensed matter physics perspective
Bibliographic record
Abstract
Theory and computational methods have long been essential tools in high-pressure research. Theoretical models can predict material behavior under extreme conditions beyond the reach of current experimental techniques. Static and dynamic simulations serve to verify these predictions and provide reliable estimates of new properties. Over the past two decades, advances in computer architecture and numerical algorithms have enabled more accurate and large-scale simulations, leading to numerous groundbreaking discoveries. More recently, the rapid expansion of artificial intelligence, mainly through machine learning-accelerated molecular dynamics, has propelled computational research into an entirely new dimension, allowing for efficient exploration of complex potential energy landscapes. This review highlights emerging trends in simulations of high-pressure processes, including new bonding behaviors, phase transitions, and element demixing. Case studies such as the formation of unconventional compounds, the immiscibility of hydrogen-helium mixtures in planetary interiors, and structural transformations and formation of diamondoid co-existing in water in carbonate melts relevant to deep Earth geochemistry demonstrate the critical insights that theoretical studies can bring to this domain. By integrating recent theoretical advancements with experimental findings, we provide a perspective on the evolving landscape of high-pressure condensed matter physics and its implications for planetary interiors and materials discovery.

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.
