Momentum dependence of the topological susceptibility with overlap fermions
Yoshiaki Koma, Ernst-Michael Ilgenfritz, Karl Koller +4
Knowledge of the derivative of the topological susceptibility at zero momentum is important for assessing the validity of the Witten-Veneziano formula for the eta' mass, and likewi…
Topological Structure of the QCD Vacuum Revealed by Overlap Fermions
E. -M. Ilgenfritz, K. Koller, Y. Koma +2
Overlap fermions preserve a remnant of chiral symmetry on the lattice. They are a powerful tool to investigate the topological structure of the vacuum of Yang-Mills theory and full…
Vacuum structure revealed by over-improved stout-link smearing compared with the overlap analysis for quenched QCD
E. -M. Ilgenfritz, D. Leinweber, P. Moran +3
A detailed comparison is made between the topological structure of quenched QCD as revealed by the recently proposed over-improved stout-link smearing in conjunction with an improv…
The chiral transition on a 24^3x10 lattice with N_f=2 clover sea quarks studied by overlap valence quarks
V. Weinberg, E. -M. Ilgenfritz, K. Koller +4
Overlap fermions are particularly well suited to study the finite temperature dynamics of the chiral symmetry restoration transition of QCD, which might be just an analytic crossov…
Localization of overlap modes and topological charge, vortices and monopoles in SU(3) LGT
E. -M. Ilgenfritz, K. Koller, Y. Koma +4
We present selected recent results of the QCDSF collaboration on the localization and dimensionality of low overlap eigenmodes and of the topological density in the quenched SU(3)…
Exploring the structure of the quenched QCD vacuum with overlap fermions
E. -M. Ilgenfritz, K. Koller, Y. Koma +3
Overlap fermions have an exact chiral symmetry on the lattice and are thus an appropriate tool for investigating the chiral and topological structure of the QCD vacuum. We study va…
Vacuum structure as seen by overlap fermions
E. -M. Ilgenfritz, K. Koller, Y. Koma +3
Three complementary views on the QCD vacuum structure, all based on eigenmodes of the overlap operator, are reported in their interrelation: (i) spectral density, localization and…
The QCD vacuum probed by overlap fermions
V. Weinberg, E. -M. Ilgenfritz, K. Koller +3
We summarize different uses of the eigenmodes of the Neuberger overlap operator for the analysis of the QCD vacuum, here applied to quenched configurations simulated by means of th…

Overlap fermions implement exact chiral symmetry on the lattice and are thus an appropriate tool for investigating the chiral and topological structure of the QCD vacuum. We study…
Probing the chiral phase transition of N_f=2 clover fermions with valence overlap fermions
V. Weinberg, E. -M. Ilgenfritz, K. Koller +3
Overlap fermions are a powerful tool for investigating the chiral and topological structure of the vacuum and the thermal states of QCD. We study various chiral and topological asp…
Localization properties of the topological charge density and the low lying eigenmodes of overlap fermions
Y. Koma, E. -M. Ilgenfritz, K. Koller +3
Overlap fermions, which preserve exact chiral symmetry on the lattice, provide a powerful tool for investigating the topological structure of the vacuum. Applying this formulation…
