Monopoles , Polyakov - Loops and Gauge Fixing on the Torus 1
We consider pure Yang Mills theory on the four torus. A set of non-Abelian transition functions is presented which encompass all instanton sectors. It is argued that these transition functions are a convenient starting point for gauge fixing. In particular, we give an extended Abelian projection with respect to the Polyakov loop, where A0 is independent of time and in the Cartan subalgebra. In ...

متن کاملGauge Fixing on the Lattice without Ambiguity
A new gauge fixing condition is discussed, which is (lattice) rotation invariant, has the ‘smoothness’ properties of the Landau gauge but can be efficiently computed and is unambiguous for almost all lattice gauge field configurations. ∗on leave from HLRZ c/o KFA Jülich, P.O.

متن کاملGeneral Computations Without Fixing the Gauge
Abstract. Within the framework of a manifestly gauge invariant exact renormalization group for SU(N) Yang-Mills, we derive a simple expression for the expectation value of an arbitrary gauge invariant operator. We illustrate the use of this formula, which takes a particularly appealing form in perturbation theory, by computing the O(g) correction to the rectangular, Euclidean Wilson loop with s...
متن کاملGauge fixing and extended Abelian monopoles in SU(2) gauge theory in 2+1 dimensions.
Extended Abelian monopoles are investigated in SU(2) lattice gauge theory in three dimensions. Monopoles are computed by Abelian projection in several gauges, including the maximal Abelian gauge. The number Nm of extended monopoles in a cube of sizem3 (in lattice units) is defined as the number of elementary (13) monopoles minus antimonopoles in the cube (m = 1, 2, . . .). The distribution of 1...
