We find, in close analogy to abelian dominance in maximal abelian gauge, the phenomenon of center dominance in maximal center gauge for $SU(2)$ lattice gauge theory. Maximal center gauge is a gauge-fixing condition that preserves a residual $Z_2$ gauge symmetry; ``center projection'' is the projection of $SU(2)$ link variables onto $Z_2$ center elements, and ``center dominance'' is the fact that the center-projected link elements carry most of the information about the string tension of the… 
Large center vortices and confinement in 3D Z(2) gauge theory
We study the role of large clusters of center vortices in producing confinement in $3\mathrm{D}$ ${Z}_{2}$ gauge theory. First, we modify each configuration of a Monte Carlo\char21{}generated
Center vortices as sources of Abelian dominance in pure SU(2) Yang-Mills theory
We argue that in the infrared regime of continuum Yang-Mills theory, the possibility of a mass gap in the charged sector is closely associated with the center vortex sector. The analysis of the
Effective theory of the D = 3 center vortex ensemble
By means of lattice calculations, center vortices have been established as the infrared dominant gauge field configurations of Yang–Mills theory. In this work, we investigate an ensemble of center
Probing center vortices and deconfinement in $\mathrm{SU}(2)$ lattice gauge theory with persistent homology
We investigate the use of persistent homology, a tool from topological data analysis, as a means to detect and quantitatively describe center vortices in SU(2) lattice gauge theory in a
Diagonal deformations of thin center vortices and their stability in Yang-Mills theories
The importance of center vortices for the understanding of the confining properties of SU(N) Yang-Mills theories is well established in the lattice. However, in the continuum, there is a problem
4D ensembles of percolating center vortices and monopole defects: The emergence of flux tubes withN-ality and gluon confinement
Ensembles of magnetic defects represent quantum variables that have been detected and extensively explored in lattice ${\rm SU}(N)$ pure Yang-Mills theory. They successfully explain many properties
Introducing vortices in the continuum using direct and indirect methods
Inspired by direct and indirect maximal center gauge methods which confirm the existence of vortices in lattice calculations and by using the connection formalism, we show that under some appropriate
STATUS OF CENTER DOMINANCE IN VARIOUS CENTER GAUGES
We review arguments for center dominance in center gauges wh re vortex locations are correctly identified. We introduce an a ppealing interpretation of the maximal center gauge, discuss problems with
