Learning the generating functional for variance reduction in lattice QCD
Ryan Abbott, Yang Fu, Daniel C. Hackett +3
The generating functional in quantum field theory provides the natural framework for constructing correlation functions as derivatives with respect to source operators. We present…

The Causal Bootstrap: Bounding Smeared Spectral Functions from Non-Perturbative Euclidean Data
Ryan Abbott, Sarah Fields, William I. Jay +2
This work introduces the causal bootstrap, a framework for bounding smeared spectral observables from finite non-perturbative Euclidean data. The method optimizes over the convex s…

Variance reduction in lattice QCD observables via normalizing flows
Ryan Abbott, Denis Boyda, Yang Fu +5
Normalizing flows can be used to construct unbiased, reduced-variance estimators for lattice field theory observables that are defined by a derivative with respect to action parame…
