Chirally improved Dirac operators: Studying the sensitivity to topological excitations for zero and finite temperature
Christof Gattringer, Meinulf Göckeler, C. B. Lang +3
We discuss the construction and properties of an approximate solution of the Ginsparg-Wilson equation, the so-called chirally improved lattice Dirac operator. In particular we stud…
Comparing lattice Dirac operators in smooth instanton backgrounds
Christof Gattringer, Meinulf Göckeler, C. B. Lang +2
We compare the behavior of different lattice Dirac operators in gauge backgrounds which are lattice discretizations of a classical instanton. In particular we analyze the standard…
Properties of near-zero modes and chiral symmetry breaking
Christof Gattringer, Meinulf Goeckeler, P. E. L. Rakow +2
We study localization and chirality properties of eigenvectors of the lattice Dirac operator. In particular we focus on the dependence of our observables on the size of the corresp…
A comprehensive picture of topological excitations in finite temperature lattice QCD
Christof Gattringer, Meinulf Göckeler, P. E. L. Rakow +2
We study spectra, localization properties and local chirality of eigenvectors of the lattice Dirac operator. We analyze ensembles of quenched SU(3) configurations on both sides of…
