Phase structure of an Abelian two-Higgs model and high temperature superconductors
M. N. Chernodub, E. -M. Ilgenfritz, A. Schiller
We study the phase structure of a three dimensional Abelian Higgs model with singly- and doubly-charged scalar fields coupled to a compact Abelian gauge field. The model is pretend…
Probing the topological structure of the QCD vacuum with overlap fermions
E. -M. Ilgenfritz, K. Koller, Y. Koma +3
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 Aoki phase with N_f=2 Wilson fermions at finite temperature
E. -M. Ilgenfritz, W. Kerler, M. Müller-Preussker +2
In this letter we report on a numerical investigation of the Aoki phase in the case of finite temperature which continues our former study at zero temperature. We have performed si…
Landau gauge ghost and gluon propagators and the Faddeev-Popov operator spectrum
A. Sternbeck, E. -M. Ilgenfritz, M. Müller-Preussker +1
In this talk we report on a recent lattice investigation of the Landau gauge gluon and ghost propagators in pure SU(3) lattice gauge theory with a special emphasis on the Gribov co…
Laplacian modes as a filter
Falk Bruckmann, Ernst-Michael Ilgenfritz
We compute low-lying eigenmodes of the gauge covariant Laplace operator on the lattice at finite temperature. For classical configurations we show how the lowest mode localizes the…
Spectral properties of the Landau gauge Faddeev-Popov operator in lattice gluodynamics
A. Sternbeck, E. -M. Ilgenfritz, M. Mueller-Preussker
Recently we reported on the infrared behavior of the Landau gauge gluon and ghost dressing functions in SU(3) Wilson lattice gluodynamics with special emphasis on the Gribov proble…
