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…

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…
