Recent advances in high energy QCD experiments probing the deconfinement transition from hadronic to coloured quark matter tend to confirm that perlocation of unbounded quarks could provide a signature of this phase transition. In the strong coupling limit the partition function of SU(2) pure gauge theory can be modeled by that of an infinite spin Ising system with short-range ferromagnetic interactions. We derive the Wolff-random cluster representation for these spin models and show that, at least in these cases, the thermal and geometrical phase transitions indeed coincide. Moreover, our results are presented in a more general setting (e.g., q-states Potts variable and/or long range interactions allowing a generalisation to a variety of physical systems.)

“…It is now well established [1,4,10,12,23] that the characteristics of one system can be completely expressed in terms of the other. In particular the critical behavior (if any) of the spin-system translates directly into critical geometrical behavior in the corresponding random cluster model.…”

“…Indeed, in the Ising (and also Potts) model, a lowtemperature symmetry breaking occurs even in some recurrent dimensions; e.g., in d = 2 for the nearest-neighbor interactions. For what determines the presence and absence of symmetry breaking in d = 1, see the work of Aizenman, Chayes, Chayes and Newman [3] and references therein.…”

“…When q ≥ 1, the associated probability measure satisfies the FKG lattice condition (see Refs. 1,12), and therefore satisfies the FKG inequality (which may be stated roughly as 'increasing events are positively correlated'). This useful inequality implies properties of stochastic comparison which are of substantial value in studying any associated phase transition.…”

×ØÖØº A principal technique for studying percolation, (ferromagnetic) Ising, Potts, and random-cluster models is the FKG inequality, which implies certain stochastic comparison inequalities for the associated probability measures. The first result of this paper is a new comparison inequality, proved using an argument developed in Refs. 2, 6, 14, and 21 in order to obtain strict inequalities for critical values. As an application of this inequality, we prove that the critical point p c (q), of the random-cluster model with cluster-weighting factor q (≥ 1), is strictly monotone in q. Our second result is a 'BK inequality' for the disjoint occurrence of increasing events, in a weaker form than that available in percolation theory.
