Strange quark mass and Lambda parameter by the ALPHA collaboration
Marina Marinkovic, Stefan Schaefer, Rainer Sommer +1
We determine f_K for lattice QCD in the two flavor approximation with non-perturbatively improved Wilson fermions. The result is used to set the scale for dimensionful quantities i…
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…
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…
Testing trivializing maps in the Hybrid Monte Carlo algorithm
Georg P. Engel, Stefan Schaefer
We test a recent proposal to use approximate trivializing maps in a field theory to speed up Hybrid Monte Carlo simulations. Simulating the CP^{N-1} model, we find a small improvem…
