Diffusion Model Predicts Crystal Structures from X-Ray Diffraction Data

Researchers have developed XRDiff, a novel diffusion model capable of predicting crystal structures from powder X-ray diffraction (PXRD) data. This model can infer structures based on known stoichiometry or, more challenging, elemental composition and unit cell atom count. XRDiff demonstrates strong performance in differentiating between polymorphs using simulated data and shows promise for generalization to experimental data through a peak-based encoding that is robust to noise and artifacts.
