First constraints on the nonperturbative gluon Collins-Soper kernel
Artur Avkhadiev, Yang Fu, Phiala E. Shanahan +2
The gluon Collins-Soper kernel, which encodes the rapidity evolution of transverse-momentum-dependent gluon distributions, is constrained for the first time in the nonperturbative…
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…
Variance reduction in lattice QCD observables via normalizing flows
Ryan Abbott, Denis Boyda, Yang Fu +6
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…
Excited-state uncertainties in lattice-QCD calculations of hadron masses and scattering phase shifts
William Detmold, Anthony V. Grebe, Daniel C. Hackett +4
Lattice QCD has historically produced energy results interpretable as either estimates relying on implicit assumptions about asymptotic behavior or one-sided upper bounds. New Lanc…
Excited-state uncertainties in lattice-QCD calculations of multi-hadron systems
William Detmold, Anthony V. Grebe, Daniel C. Hackett +4
Excited-state effects lead to hard-to-quantify systematic uncertainties in lattice quantum chromodynamics (LQCD) spectroscopy calculations when computationally accessible imaginary…
Lattice field theory for superconducting circuits
Joshua Lin, Max Hays, Stephen Sorokanich +3
Large superconducting quantum circuits have a number of important applications in quantum computing. Accurately predicting the performance of these devices from first principles is…
