Diffusion models applied to O(3) nonlinear sigma model

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a score-based diffusion model to analyze the two-dimensional classical Heisenberg model, which represents the O(3) nonlinear sigma model. This approach utilizes a multiscale sampling scheme implemented through neural networks trained on different coarse-grainings of the data, aiming to improve sampling accuracy and computational efficiency. The study also introduces Stein diagnostics for evaluating the quality of the learned score and discusses technical considerations for applying diffusion models to spheres, including input lifting and boundary-layer approximations.

    Diffusion models for the $O(3)$ nonlinear sigma model

    arXiv:2610.39568v2 Announce Type: replace-cross Abstract: A score-based diffusion model is trained on the two-dimensional classical Heisenberg model, the lattice representation of the $O(3)$ nonlinear sigma model. Neural networks are trained on three different coarse-grainings of…
