Investigation of the phase structure of a chirally-invariant Higgs-Yukawa model
John Bulava, Philipp Gerhold, George W. -S. Hou +6
We present new data on our ongoing project on the investigation of the phase structure of the Higgs-Yukawa model at large bare Yukawa couplings. The data presented last year are ex…
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…
Exploring Topology Conserving Gauge Actions for Lattice QCD
W. Bietenholz, K. Jansen, K. -I. Nagai +3
We explore gauge actions for lattice QCD, which are constructed such that the occurrence of small plaquette values is strongly suppressed. By choosing strong bare gauge couplings w…
Scaling test of fermion actions in the Schwinger model
N. Christian, K. Jansen, K. Nagai +1
We discuss the scaling behaviour of different fermion actions in dynamical simulations of the 2-dimensional massive Schwinger model. We have chosen Wilson, hypercube, twisted mass…
Testing Topology Conserving Gauge Actions for Lattice QCD
K. -i. Nagai, K. Jansen, W. Bietenholz +3
We explore gauge actions for lattice QCD, which are constructed such that the occurrence of small plaquette values is strongly suppressed. Such actions originate from the admissibi…
Twisted mass fermions: neutral pion masses from disconnected contributions
F. Farchioni, K. Jansen, C. McNeile +12
Twisted mass fermions allow light quarks to be explored but with the consequence that there are mass splittings, such as between the neutral and charged pion. Using a direct calcul…
