Progress in generating gauge ensembles with Stabilized Wilson Fermions
Francesca Cuteri, Anthony Francis, Patrick Fritzsch +5
The continued generation of quark flavor gauge configurations using stabilized Wilson fermions by the open lattice initiative (OpenLat) is reported. We present the status…
Non-perturbative strong coupling at timelike momenta

We compute the strong coupling constant of Landau gauge QCD in the full complex momentum plane, both directly and via spectral reconstruction. In particular, we consider the Taylor…
Translating topological benefits in very cold lattice simulations
Mattia Bruno, Marco Cè, Anthony Francis +3
Master-field simulations offer an approach to lattice QCD in which calculations are performed on a small number of large-volume gauge-field configurations. The latter is advantageo…
