MiAD: Mirage Atom Diffusion for De Novo Crystal Generation

arXiv:2511.14426v2 Announce Type: replace Abstract: In recent years, diffusion-based models have demonstrated exceptional performance in searching for simultaneously stable, unique, and novel (S.U.N.) crystalline materials. However, most of these models don't have the ability to change the number of atoms in the crystal during the generation process, which limits the variability of model sampling trajectories. In this paper, we demonstrate the severity of this restriction and introduce a simple yet powerful technique, mirage infusion, which enables diffusion models to change the state of the a

Why this matters
Why now

The continuous advancements in AI, particularly diffusion models, are pushing the boundaries of generative design in materials science, making this innovation a natural progression.

Why it’s important

This development could significantly accelerate the discovery and design of novel materials with specific properties, impacting multiple industries reliant on advanced materials.

What changes

Diffusion models can now dynamically adjust the number of atoms during crystal generation, enabling the creation of a wider and more diverse range of stable, unique, and novel (S.U.N.) crystalline materials.
