Complex-momentum form factors from lattice QCD
Maxwell T. Hansen, Gurtej Kanwar
We demonstrate that form factors evaluated with momenta analytically continued into the complex plane can be accessed directly from position-space Euclidean correlators such as tho…
String dynamics of a (2+1)D U(1) quantum link model on a digital quantum computer
Anthony Gandon, Alessandro Mariani, Debasish Banerjee +5
The (2+1)D U(1) pure gauge theory always exists in the confining phase, with strings of non-zero string tension giving a characteristic linear potential between static charges. Thi…
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…
Normalizing flows for all-orders QED corrections in lattice field theory
Nils Hermansson-Truedsson, Gurtej Kanwar
This work develops a framework to apply normalizing-flow transformations of field configurations for all-orders Quantum Electrodynamics (QED) corrections in lattice field theory. T…
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…
A Monte Carlo estimator of flow fields for sampling and noise problems
Michael S. Albergo, Gurtej Kanwar
Learned field transformations may help address ubiquitous critical slowing down and signal-to-noise problems in lattice field theory. In the context of an annealed sequence of dist…
