21 Dec 2009 | Abstract: | We reveal the center vortex content of SU(2) calorons and ensembles of them.
We use Laplacian Center Gauge as well as Maximal Center Gauges to show that the
vortex in a single caloron consists of two parts. The first one connects the
constituent dyons of the caloron (which are monopoles in Laplacian Abelian
Gauge) and extends in time. The second part is predominantly spatial, encloses
one of the dyons and can be related to the twist in the caloron gauge field.
This part depends strongly on the caloron holonomy and degenerates to a plane
when the holonomy is maximally nontrivial, i.e. when the asymptotic Polyakov
loop is traceless. Correspondingly, we find the spatial vortices in caloron
ensembles to percolate in this case. This finding fits perfectly in the
confinement scenario of vortices and shows that calorons are suitable to
facilitate the vortex confinement mechanism. | Source: | arXiv, 0912.4186 | Services: | Forum | Review | PDF | Favorites |
