Recent Results on the Abelian Projection of Lattice Gluodynamics
We do not have much intuition in nonabelian theories, whereas our understanding of the Maxwell equations and abelian theories is far better. For this reason people are trying to explain the confinement phenomenon in terms of the abelian projection of nonabelian theory [1]. Different abelian projections lead to different abelian theories, and now it is clear that there exist at least one abelian...
متن کاملLaplacian Abelian Projection
A new partial gauge fixing condition for the abelian projection is introduced. It is based on the lowest-lying eigenvector of a covariant Laplacian operator. This gauge is smooth and free of lattice Gribov copies. These properties are important for an unambiguous computation of the abelian projected gauge field configuration.
متن کاملTheory of Abelian Projection
Analytic methods for Abelian projection are developed. A number of results are obtained related to string tension measurements. It is proven that even without gauge fixing, abelian projection yields string tensions of the underlying non-Abelian theory. Strong arguments are given for similar results in the case where gauge fixing is employed. The methods used emphasize that the projected theory ...
متن کاملAbelian Projection without Ambiguities
Laplacian Abelian Projection is discussed. This term refers to the use of a new (“Laplacian”) gauge fixing prescription for implementing the Abelian Projection of QCD. The gauge condition is based on the lowest-lying eigenvector of the covariant Laplacian operator in the adjoint representation. This Laplacian gauge fixing procedure is free of the ambiguities which plague lattice simulations whi...
متن کاملLaplacian 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...
