Hadronic light-by-light contribution to the muon using twisted-mass fermions
Nikolaos Kalntis, Gurtej Kanwar, Marcus Petschlies +2
We report on our preliminary results from the lattice-QCD computation of the hadronic light-by-light (HLbL) contribution to the anomalous magnetic moment of the muon. We use twiste…
Exploring gauge-fixing conditions with gradient-based optimization
William Detmold, Gurtej Kanwar, Yin Lin +2
Lattice gauge fixing is required to compute gauge-variant quantities, for example those used in RI-MOM renormalization schemes or as objects of comparison for model calculations. R…
Practical applications of machine-learned flows on gauge fields
Ryan Abbott, Michael S. Albergo, Denis Boyda +5
Normalizing flows are machine-learned maps between different lattice theories which can be used as components in exact sampling and inference schemes. Ongoing work yields increasin…
Multiscale Normalizing Flows for Gauge Theories
Ryan Abbott, Michael S. Albergo, Denis Boyda +5
Scale separation is an important physical principle that has previously enabled algorithmic advances such as multigrid solvers. Previous work on normalizing flows has been able to…
Multi-particle interpolating operators in quantum field theories with cubic symmetry
William Detmold, William I. Jay, Gurtej Kanwar +2
Numerical studies of lattice quantum field theories are conducted in finite spatial volumes, typically with cubic symmetry in the spatial coordinates. Motivated by these studies, t…
Flow-based sampling for lattice field theories
Gurtej Kanwar
Critical slowing down and topological freezing severely hinder Monte Carlo sampling of lattice field theories as the continuum limit is approached. Recently, significant progress h…
