“…Note that these locations are part of the LCG vortex surface by definition. Similar monopole worldlines have been obtained in the MAG [8,32]. Adjoint fermionic zero modes, on the other hand, detect the constituent dyons by maxima [33].…”

We reveal the center vortex content of SUð2Þ 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.

“…To complete the analysis of the ground-state dynamics the Yang-Mills equations 1 for the (coarse-grained) gauge fields in the topologically trivial sector is solved subject to a source term provided by φ: A pure-gauge solution exists which shifts the vanishing energy density and pressure due to the noninteracting, BPS saturated caloron and anticaloron to finite values, P gs = −ρ gs = −4πΛ 3 T . Microscopically, the negative ground state pressure is due to the (anti)caloron's holonomy shift by gluon exchange generating a constituent monopole and antimonopole [4,5,6,7,8] subject to a mutual force induced by quantum fluctuations [9]. Notice that attraction is much more likely than repulsion [1] explaining the negative ground-state pressure that emerges after spatial coarse-graining.…”

We compute the one-loop polarization tensor Π for the on-shell, massless mode in a thermalized SU(2) Yang-Mills theory being in its deconfining phase. Postulating that SU(2) CMB today = U(1) Y , we discuss Π's effect on the lowmomentum part of the black-body spectrum at temperatures ∼ 2 · · · 4 T CMB where T CMB ∼ 2.73 K. A table-top experiment is proposed to test the above postulate. As an application, we point out a possible connection with the stability of dilute, cold, and old innergalactic atomic hydrogen clouds. We also compute the two-loop correction to the pressure arising from the instantaneous massless mode in unitary-Coulomb gauge, which formerly was neglected, and present improved estimates for subdominant corrections.

“…But for ρ/β ≫ 1 the situation is opposite; the instanton becomes static and will dissolve in two BPS monopoles [6,7]. The transition occurs [8,9] for 1 2 β < ρ < β. When, however, the holonomy is trivial one of the monopoles is massless and will hide in the background.…”
