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…
Simulations in the epsilon-Regime of Chiral Perturbation Theory
K. -I. Nagai, W. Bietenholz, T. Chiarappa +2
We discuss the potential of Ginsparg-Wilson fermion simulations in the epsilon-regime of chiral perturbation theory, regarding the determination of the leading low energy constants…
Random Matrix Theory and the Spectra of Overlap Fermions
S. Shcheredin, W. Bietenholz, T. Chiarappa +2
The application of Random Matrix Theory to the Dirac operator of QCD yields predictions for the probability distributions of the lowest eigenvalues. We measured Dirac operator spec…
Naturally Light Fermions from Dimensional Reduction
W. Bietenholz, A. Gfeller, U. -J. Wiese
We consider the 3-d Gross-Neveu model in the broken phase and construct a stable brane world by means of a domain wall and an anti-wall. Fermions of opposite chirality are localize…
Axial Anomaly and Index of the Overlap Hypercube Operator
David H. Adams, Wolfgang Bietenholz
The overlap hypercube fermion is constructed by inserting a lattice fermion with hypercubic couplings into the overlap formula. One obtains an exact Ginsparg-Wilson fermion, which…
Spectral Properties of the Overlap Dirac Operator in QCD
W. Bietenholz, K. Jansen, S. Shcheredin
We discuss the eigenvalue distribution of the overlap Dirac operator in quenched QCD on lattices of size 8^{4}, 10^{4} and 12^{4} at β= 5.85 and β= 6. We distinguish the topologica…
