Laplacian Abelian Projection: Abelian dominance and Monopole dominance

Despite its many successes, the Maximally Abelian Gauge (MAG) [1] has the great drawback that it is ambiguous. A precise way to phrase this ambiguity is as follows: it is in general unlikely, and certainly impossible to guarantee, that the configuration obtained by the usual local iterative minimization algorithm be (arbitrarily) close to the desired configuration {Ūμ,x = Ω̄xUμ,xΩ̄ + x+μ̂}, no mat...

Gauge independence of Abelian and monopole dominance

We formulate a stochastic gauge fixing method to study the gauge dependence of Abelian projection. In this method, one can change the gauge from the maximally Abelian one to no gauge fixing continuously. We have found that the linear part of the heavy quark potential from Abelian contribution depends little on the gauge parameter. Similar results have been obtained for the monopole contribution...

Abelian Magnetic Monopole Dominance in Quark Confinement

We prove Abelian magnetic monopole dominance in the string tension of QCD. Abelian and monopole dominance in low energy physics of QCD has been confirmed for various quantities by recent Monte Carlo simulations of lattice gauge theory. In order to prove this dominance, we use the reformulation of continuum Yang-Mills theory in the maximal Abelian gauge as a deformation of a topological field th...

Monopole Fields from Vortex Sheets Reconciling Abelian and Center Dominance

We describe a new order parameter for the confinement-deconfinement transition in lattice SU(2) Yang-Mills theory. It is expressed in terms of magnetic monopole field correlators represented as sums over sheets of center vortices. Our construction establishes a link between “abelian” and “center dominance”. It avoids an inconsistency in the treatment of small scales present in earlier definitio...

Vortex Structure vs. Monopole Dominance in Abelian-Projected Gauge Theory

We find that Polyakov lines, computed in abelian-projected SU(2) lattice gauge theory in the confined phase, have finite expectation values for lines corresponding to two units of the abelian electric charge. This means that the abelian-projected lattice has at most Z2, rather than U(1), global symmetry. We also find a severe breakdown of the monopole dominance approximation, as well as positiv...
