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…
Order-separated tensor-network method for QCD in the strong-coupling expansion
Thomas Samberger, Jacques Bloch, Robert Lohmayer +1
We introduce the order-separated Grassmann higher-order tensor renormalization group (OS-GHOTRG) method for QCD with staggered quarks in the strong-coupling expansion. The method 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…
Tensor-network formulation of QCD in the strong-coupling expansion
Thomas Samberger, Jacques Bloch, Robert Lohmayer +1
We present a tensor-network formulation for the strong-coupling expansion of QCD with staggered quarks at nonzero chemical potential, for arbitrary number of dimensions, colors, an…
Gauge-equivariant pooling layers for preconditioners in lattice QCD
Christoph Lehner, Tilo Wettig
We demonstrate that gauge-equivariant pooling and unpooling layers can perform as well as traditional restriction and prolongation layers in multigrid preconditioner models for lat…
Provenance for Lattice QCD workflows
Tanja Auge, Gunnar Bali, Meike Klettke +4
We present a provenance model for the generic workflow of numerical Lattice Quantum Chromodynamics (QCD) calculations, which constitute an important component of particle physics r…
