Center vortex influence on the Dirac spectrum
Urs Heller, R. Hoellwieser, M. Faber +2
We study the influence of center vortices on the low-lying eigenmodes of the Dirac operator, in both the overlap and asqtad formulations. For center-projected configurations, one f…
Casimir scaling in G(2) lattice gauge theory
L. Liptak, S. Olejnik
We computed potentials between static color sources from the six lowest representations of G(2) lattice gauge theory, in numerical simulations with the Wilson action on asymmetric…
A first look at Landau-gauge propagators in G2 Yang-Mills theory
Axel Maas, Stefan Olejnik
G_2 Yang--Mills theory is an interesting laboratory to investigate non-perturbative effects. On one hand, no conventional quark confinement via a linearly rising potential is prese…
Color Screening, Casimir Scaling, and Domain Structure in G(2) and SU(N) Gauge Theories
J. Greensite, K. Langfeld, S. Olejnik +2
We argue that screening of higher-representation color charges by gluons implies a domain structure in the vacuum state of non-abelian gauge theories, with the color magnetic flux…
Peculiarities in the Spectrum of the Adjoint Scalar Kinetic Operator in Yang-Mills Theory
J. Greensite, A. V. Kovalenko, S. Olejnik +3
We study the spectrum of low-lying eigenmodes of the kinetic operator for scalar particles, in the color adjoint representation of Yang-Mills theory. The kinetic operator is the co…
Eigenmodes of covariant Laplacian in SU(2) Yang-Mills vacuum: higher representations
J. Greensite, S. Olejnik, M. I. Polikarpov +2
The study of lowest eigenmodes of the covariant Laplacian in fundamental representation of the gauge group revealed their specific localization properties. These may bear informati…
