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…
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…
Duality of gauge field singularities and the structure of the flux tube in Abelian-projected SU(2) gauge theory and the dual Abelian Higgs model
Y. Koma, M. Koma, E. -M. Ilgenfritz +2
The structure of the flux-tube profile in Abelian-projected (AP) SU(2) gauge theory in the maximally Abelian gauge is studied. The connection between the AP flux tube and the class…
