phi4-generative/2d-phi4-configs

2D φ⁴ lattice field configurations Monte Carlo configurations of the two-dimensional scalar φ⁴ theory on periodic square lattices, generated for training and benchmarking generative models (score-based diffusion), and for unsupervised-learning studies of the phase transition (PCA).
