SSCHA-based Evolutionary Crystal Structure Prediction with Quantum Nuclear Motion
Analysis
Key Takeaways
- •Integrates MLIPs with SSCHA for finite-temperature CSP.
- •Compares active-learning and universal MLIP approaches.
- •Highlights the importance of quantum anharmonicity for accurate stability rankings.
- •Extends CSP to systems where quantum nuclear motion and anharmonicity dominate.
“Including quantum anharmonicity simplifies the free-energy landscape and is essential for correct stability rankings, that is especially important for high-temperature phases that could be missed in classical 0 K CSP.”
