Sampling the Schwinger Model with Gauge-Equivariant Diffusion
Octavio Vega, Aida X. El-Khadra
We present a first study of a diffusion-based approach to accelerated sampling of the lattice Schwinger model. Our work is inspired by recent and growing successes in dev…
Spectral Diffusion for Sampling on
Gurtej Kanwar, Octavio Vega
Although ensemble generation remains a central challenge in lattice field theory simulations, recent advances in generative modeling may offer a path to accelerated sampling in the…
Group-Equivariant Diffusion Models for Lattice Field Theory
Octavio Vega, Javad Komijani, Aida El-Khadra +1
Near the critical point, Markov Chain Monte Carlo (MCMC) simulations of lattice quantum field theories (LQFT) become increasingly inefficient due to critical slowing down. In this…
Using AI for Efficient Statistical Inference of Lattice Correlators Across Mass Parameters
Octavio Vega, Andrew Lytle, Jiayu Shen +1
Lattice QCD is notorious for its computational expense. Modern lattice simulations require large-scale computational resources to handle the large number of Dirac operator inversio…
