Calorons, instantons and constituent monopoles in SU(3) lattice gauge theory
Christof Gattringer
We analyze the zero-modes of the Dirac operator in quenched SU(3) gauge configurations at non-zero temperature and compare periodic and anti-periodic temporal boundary conditions f…
Recent results from systematic parameterizations of Ginsparg-Wilson fermions
Christof Gattringer
The Fixed Point Dirac Operator and Chirally Improved Fermions both use large numbers of gauge paths and the full Dirac structure to approximate a solution of the Ginsparg-Wilson eq…
Quenched QCD with fixed-point and chirally improved fermion
Christof Gattringer, Meinulf Göckeler, Peter Hasenfratz +9
In this contribution we present results from quenched QCD simulations with the parameterized fixed-point (FP) and the chirally improved (CI) Dirac operator. Both these operators ar…
The topological susceptibility of SU(3) gauge theory near T_c
Christof Gattringer, Roland Hoffmann, Stefan Schaefer
We compute the topological susceptibility chi_t in SU(3) lattice gauge theory using fermionic methods based on the Atiyah-Singer index theorem. Near the phase transition we find a…
Chiral symmetry restoration and the Z3 sectors of QCD
Christof Gattringer, P. E. L. Rakow, Andreas Schaefer +1
Quenched SU(3) lattice gauge theory shows three phase transitions, namely the chiral, the deconfinement and the Z3 phase transition. Knowing whether or not the chiral and the decon…
Testing the self-duality of topological lumps in SU(3) lattice gauge theory
Christof Gattringer
We discuss a simple formula which connects the field-strength tensor to a spectral sum over certain quadratic forms of the eigenvectors of the lattice Dirac operator. We analyze th…
