PhononBench:A Large-Scale Phonon-Based Benchmark for Dynamical Stability in Crystal Generation
arXiv:2512.21227v3 Announce Type: replace-cross Abstract: In recent years, generative artificial intelligence has made significant advances in the design of crystalline materials, giving rise to approaches based on graph neural networks, diffusion models, and large language models. Existing evaluations commonly follow the stability-uniqueness-novelty (S.U.N.) framework, where stability is primarily assessed using thermodynamic criteria, which do not fully capture the dynamical stability essential for a material's practical existence. Dynamical stability is a key determinant of whether a materi
Generative AI for material science is advancing rapidly, necessitating more sophisticated evaluation benchmarks like PhononBench to assess practical material stability.
This development improves AI's ability to design stable and practically viable crystalline materials, accelerating R&D in critical sectors like manufacturing and energy.
The criteria for evaluating AI-generated materials are expanding beyond thermodynamic stability to include crucial dynamical stability, leading to more robust AI designs.
