Vortices and confinement in hot and cold D = 2+1 gauge theories

Abstract: Abstract.We calculate the variation with temperature of the vortex free energy in D=2+1 SU(2) lattice gauge theories. We do so both above and below the deconfining transition at T = T c . We find that this quantity is zero at all T for large enough volumes. For T < T c this observation is consistent with the fact that the phase is linearly confining; while for T > T c it is consistent with the conventional expectation of 'spatial' linear confinement. In small spatial volumes this quantity is shown to be non-ze… Show more

“…We see that our results in eqn (24) and eqn (25) are consistent, at the 2σ level, with both these expectations, within quite small errors; with perhaps a slight bias towards favouring MQCD. It is because the two sets of predictions are numerically very similar that we cannot, at present, choose between them.…”

“…Another interesting question is how the string tension ratios, whether given by MQCD or Casimir scaling, reflect themselves in k-vortex condensates, in the dual disorder loop approach to confinement [28], and whether this exposes any simple duality between Wilson loops and 't Hooft disorder loops. A calculation, illustrating how one might proceed, was outlined in [5,24]. A similar question can be posed in monopole models of confine-ment, following upon the simple model calculations of higher charged string tensions in [29], after Abelian projection, and in [27] with adjoint monopoles (at high T ).…”

“…A precise relationship between such a gauge-fixed, so called P-vortices and the topological center vortices originally introduced by 't Hooft[52] is still missing. The interested reader is referred to Refs [53][54][55][56][57][58][59][60][61][62][63][64][65]. for further discussions on the subject.…”

“…Similar expressions will hold for any direction β A = f (β F ) along which the continuum limit β F → ∞ is taken. 18 At T > 0 one can simply substitute L 2 → L s · L t in Eqs. (18,19,22,23).…”

“…Among these center vortices [12][13][14] have enjoyed broad attention, in particular in the lattice literature. Although most of the effort was put in dealing with gauge fixed schemes, 1 some investigations actually attempted to tackle the problem in a gauge invariant way [17][18][19][20][21][22][23] and are therefore directly related to 't Hooft's original idea.…”
