Quantitative comparison of filtering methods in lattice QCD
Falk Bruckmann, Christof Gattringer, Ernst-Michael Ilgenfritz +3
We systematically compare filtering methods used to extract topological excitations (like instantons, calorons, monopoles and vortices) from lattice gauge configurations, namely AP…
Topology and confinement at T \neq 0 : calorons with non-trivial holonomy
P. Gerhold, E. -M. Ilgenfritz, M. Müller-Preussker +2
In this talk, relying on experience with various lattice filter techniques, we argue that the semiclassical structure of finite temperature gauge fields for T < T_c is dominated by…
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…
Twisted mass QCD thermodynamics: first results on apeNEXT
E. -M. Ilgenfritz, M. Müller-Preussker, A. Sternbeck +4
The motivations for simulating QCD thermodynamics with Wilson fermions and a twisted mass term are introduced. The twisted mass approach provides a natural infrared cutoff and O(a)…
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…
Lattice study of the infrared behavior of QCD Green's functions in Landau gauge
A. Sternbeck, E. -M. Ilgenfritz, M. Müller-Preussker +2
We summarize the current status of our numerical results for the gluon and ghost propagators and for the Kugo-Ojima confinement parameter in quenched SU(3) lattice Landau gauge the…
