New diffusion model generates complete crystal structures by mimicking symmetry breaking

Researchers have developed a new diffusion-based framework called Symmetry-breaking Crystal Diffusion (SbCD) for generating complete crystallographic specifications. This novel approach models symmetry-breaking dynamics using a Markovian jump-diffusion process, allowing it to traverse different space groups in a physically motivated way. SbCD aims to overcome the limitations of existing models that generate crystals only up to site symmetries and rely on sampling space groups from empirical distributions. In de novo generation experiments, SbCD demonstrated superior performance compared to its symmetry-preserving counterpart. AI
