چکیده
Abelian gauge theories formulated on a space-time lattice can be used as a prototype for investigating the confinement mechanism. In U(1) lattice gauge theory it is possible to perform a dual transformation of the path integral. Simulating the obtained dual theory (which corresponds to a certain limit of a dual Higgs model) including external sources, we perform a very accurate analysis of flux tubes with respect to the dual superconductor picture. Dual flux tube simulations are also performed in the full Abelian Higgs model, in order to obtain non-perturbative control over quantum and string fluctuations, and for a comparison to the results of dual QCD.

Analytic Estimate of the Order Parameter for Magnetic Charge Condensation in Qcd
A possible mechanism for confinement of color is Dual Superconductivity of the Vacuum 1 2 3. The idea is that magnetic charges condense in the vacuum : the chromoelectric field acting between a q− q̄ pair is channeled by dual Meissner effect into flux tubes with energy proportional to the distance. Flux tubes are indeed observed in lattice simulations , and the corresponding field configurations...

The spherically symmetric solutions in Weyl gravity interacting with U (1) or SU (2) gauge fields are examined. It is shown that these solutions are conformally equivalent to an infinite flux tube with constant (color) electric and magnetic fields. This allows us to say that Weyl gravity has in some sense a classical confinement mechanism. We discuss a possible connection with flux tubes in qua...

The mass spectrum of the 3d SU(2) Higgs model for states with quantum numbers 0 ++ , 2 ++ and 1 −− as obtained from lattice simulations is presented in the Higgs and confinement regions, both for a small and a large scalar coupling. In the latter case it is possible to continuously connect the spectra and observe the transition from confining to Higgs physics via decay of flux loops.

The ratios between string tensions σD of color-electric flux tubes in higher and fundamental SU(3) representations, dD ≡ σD/σ3, are systematically studied in a Weyl symmetric formulation of the DGL theory. The ratio is found to depend on the Ginzburg-Landau (GL) parameter, κ ≡ mχ/mB, the mass ratio between monopoles (mχ) and dual gauge bosons (mB). While the ratios dD follow a simple flux count...
