Non-renormalizability of the HMC algorithm
Martin Lüscher, Stefan Schaefer
In lattice field theory, renormalizable simulation algorithms are attractive, because their scaling behaviour as a function of the lattice spacing is predictable. Algorithms implem…
Stability of lattice QCD simulations and the thermodynamic limit
L. Del Debbio, L. Giusti, M. Lüscher +2
We study the spectral gap of the Wilson--Dirac operator in two-flavour lattice QCD as a function of the lattice spacing , the space-time volume and the current-quark mass $m…
Schwarz-preconditioned HMC algorithm for two-flavour lattice QCD
Martin Lüscher
The combination of a non-overlapping Schwarz preconditioner and the Hybrid Monte Carlo (HMC) algorithm is shown to yield an efficient simulation algorithm for two-flavour lattice Q…
A note on the practical feasibility of domain-wall fermions
P. Hernández, K. Jansen, M. Lüscher
Domain-wall fermions preserve chiral symmetry up to terms that decrease exponentially when the lattice size in the fifth dimension is taken to infinity. The associated rates of con…
