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…
A toy model of (grand) unified monopoles
Lorenz von Smekal, Torsten Tok, Philippe de Forcrand
We explore the old idea that, in a theory containing several gauge groups, the topological defects of one gauge group coincide with those of another gauge group. This simple 'unifi…
The Gluon Propagator in Lattice Landau Gauge with twisted boundary conditions
Torsten Tok, Kurt Langfeld, Hugo Reinhardt +1
We investigate the infrared behaviour of the gluon propagator in Landau gauge on a lattice with twisted boundary conditions. Analytic calculations using Dyson-Schwinger equations,…
Free Energy of thick Center Vortices
Ch. Korn, H. Reinhardt, T. Tok
The free energy of thick center vortices is calculated in continuum Yang-Mills theory in one-loop approximation using the proper time regularization. The vortices are represented b…
Center vortices and Dirac eigenmodes in SU(2) lattice gauge theory
Jochen Gattnar, Christof Gattringer, Kurt Langfeld +4
We study the interplay between Dirac eigenmodes and center vortices in SU(2) lattice gauge theory. In particular we focus on vortex-removed configurations and compare them to an en…
Spectral flow of the Dirac spectrum in intersecting vortices
H. Reinhardt, T. Tok
The spectrum of the Dirac Hamiltonian in the background of crossing vortices is studied. To exploit the index theorem, and in analogy to the lattice the space-time manifold is chos…
