Iterative methods for overlap and twisted mass fermions
T. Chiarappa, K. Jansen, K. -I. Nagai +6
We present a comparison of a number of iterative solvers of linear systems of equations for obtaining the fermion propagator in lattice QCD. In particular, we consider chirally inv…
A (P)HMC algorithm for N_f = 2 + 1 + 1 flavours of twisted mass fermions
T. Chiarappa, R. Frezzotti, C. Urbach
We present a detailed design of a (P)HMC simulation algorithm for N_f = 2 + 1 + 1 maximally twisted Wilson quark flavours. The algorithm retains even/odd and mass-shift preconditio…
Simulating chiral quarks in the epsilon-regime of QCD
W. Bietenholz, T. Chiarappa, K. Jansen +2
We present simulation results for lattice QCD with chiral fermions in small volumes, where the epsilon-expansion of chiral perturbation theory applies. Our data for the low lying D…
Comparison between overlap and twisted mass fermions towards the chiral limit
W. Bietenholz, S. Capitani, T. Chiarappa +10
We compare overlap fermions, which are chirally invariant, and Wilson twisted mass fermions in the approach to the chiral limit. Our quenched simulations reveal that with both form…
Comparing iterative methods for overlap and twisted mass fermions
T. Chiarappa, K. Jansen, K. -I. Nagai +6
We present a systematic comparison of various iterative methods to obtain the fermion propagator with both overlap and twisted mass fermions at fixed pion mass in the quenched appr…
Meson Correlation Functions in the epsilon-Regime
T. Chiarappa, W. Bietenholz, K. Jansen +2
We present a numerical pilot study of the meson correlation functions in the epsilon-regime of chiral perturbation theory. Based on simulations with overlap fermions we measured th…
