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…
An Abelian two-Higgs model and high temperature superconductivity
M. N. Chernodub, Arwed Schiller, E. -M. Ilgenfritz
We study a three dimensional Abelian Higgs model containing singly- and doubly-charged scalar fields coupled to a compact Abelian gauge field in the London limit. The model attract…
Laplacian modes for calorons and 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…
From the Abelian projected flux tube to the dual Abelian Higgs model
E. -M. Ilgenfritz
A recent detailed study of the Q-anti-Q flux tube and its DAHM analysis is reported.
On Dirac sheet configurations of SU(2) lattice fields
E. -M. Ilgenfritz, B. V. Martemyanov, M. Müller-Preussker +1
Finite temperature Euclidean SU(2) lattice gauge fields close to the deconfinement phase transition are subjected to cooling. We find relatively stable or absolutely stable configu…
A numerical reinvestigation of the Aoki phase with N_f=2 Wilson fermions at zero temperature
E. -M. Ilgenfritz, W. Kerler, M. Mueller-Preussker +2
We report on a numerical reinvestigation of the Aoki phase in lattice QCD with two flavors of Wilson fermions where the parity-flavor symmetry is spontaneously broken. For this pur…
