XRDiff: Crystal Structure Prediction from Powder X-Ray Diffraction Data Using Diffusion Models
arXiv:2606.14003v1 Announce Type: cross Abstract: Determining the crystal structure of a material from its powder X-ray diffraction (PXRD) pattern is a central challenge in materials science. PXRD is an accessible and widely used characterization technique, yet recovering the atomic structure from diffraction data requires solving an underdetermined inverse problem due to the loss of phase information. Generative modeling can provide a prior over atomic structure and learn the mapping from PXRD patterns to crystal structures via simulated structure-spectrum pairs. We present XRDiff, a diffusio
The increasing sophistication of generative AI models, specifically diffusion models, is enabling breakthroughs in complex inverse problems such as crystal structure prediction from limited data.
This development significantly accelerates materials discovery and characterization, crucial for advancements in various high-tech sectors, potentially reducing R&D costs and timelines.
The ability to accurately predict crystal structures from easily obtainable PXRD data changes the methodology for materials science research, moving from time-consuming experimental iteration to AI-assisted design.
