Learning Low-Order Approximations of the Quark Propagator in Lattice QCD
Simon Pfahler, Maren Käfferlein, Daniel Knüttel +2
The hopping expansion is an important approximation of the quark propagator in lattice quantum chromodynamics, but it diverges for light quarks, which limits the scope of strong-co…
Isospin breaking corrections to the hadronic vacuum polarization with stochastic coordinate sampling
Mattia Bruno, Vera Gülpers, Nils Hermansson-Truedsson +3
In the recent Muon g-2 Theory Initiative white paper update, the hadronic vacuum polarization (HVP) contribution -- which dominates the theoretical uncertainty -- is evaluated as a…
A novel gauge-equivariant neural-network architecture for preconditioners in lattice QCD
Simon Pfahler, Daniel Knüttel, Christoph Lehner +1
Lattice QCD simulations are computationally expensive, with the solution of the Dirac equation being the major computational bottleneck of many calculations. We introduce a novel g…
