Master-field simulations of O(a)-improved lattice QCD: Algorithms, stability and exactness
Anthony Francis, Patrick Fritzsch, Martin Lüscher +1
In master-field simulations of lattice QCD, the expectation values of interest are obtained from a single or at most a few representative gauge-field configurations on very large l…
Stochastic locality and master-field simulations of very large lattices
Martin Lüscher
In lattice QCD and other field theories with a mass gap, the field variables in distant regions of a physically large lattice are only weakly correlated. Accurate stochastic estima…
SMD-based numerical stochastic perturbation theory
Mattia Dalla Brida, Martin Lüscher
The viability of a variant of numerical stochastic perturbation theory, where the Langevin equation is replaced by the SMD algorithm, is examined. In particular, the convergence of…
The gradient flow coupling from numerical stochastic perturbation theory
Mattia Dalla Brida, Martin Lüscher
Perturbative calculations of gradient flow observables are technically challenging. Current results are limited to a few quantities and, in general, to low perturbative orders. Num…
Lattice QCD with open boundary conditions and twisted-mass reweighting
Martin Lüscher, Stefan Schaefer
Lattice QCD simulations at small lattice spacings and quark masses close to their physical values are technically challenging. In particular, the simulations can get trapped in the…
Lattice QCD without topology barriers
Martin Lüscher, Stefan Schaefer
As the continuum limit is approached, lattice QCD simulations tend to get trapped in the topological charge sectors of field space and may consequently give biased results in pract…
