Non - equilibrium signals of the SU ( 3 ) deconfining phase transition
نویسندگان
چکیده
In SU(3) simulations with the model A (Glauber) dynamics we find unambiguous signal for the transition when the (driving) temperature Tf is larger than Tc. A dynamical growth of Polyakov loop structure factors, reaching maxima which scale approximately with the volume of the system, precedes equilibration. We study their influence on various observables, using different lattice sizes to illustrate an approach to a finite volume continuum limit. Strong correlations are found during the dynamical process, but not in the deconfined phase at equilibrium. Debye screening masses mD(Tf ) are estimated from initial response to the temperature change and found to be consistent with equilibrium estimates by Kaczmarek et al.

Calorons and monopoles from smeared SU ( 2 ) lattice fields at non - zero temperature
In equilibrium, at finite temperature below and above the deconfining phase transition, we have generated lattice SU(2) gauge fields and have exposed them to smearing in order to investigate the emerging clusters of topological charge. Analysing in addition the monopole clusters according to the maximally Abelian gauge, we have been able to characterize part of the topological clusters to corre...

We report on our ongoing investigation of the deconfining phase transition in SU(4) and SU(6) gauge theories. We calculate the critical couplings while taking care to avoid the influence of a nearby bulk phase transition. We determine the latent heat of the phase transition and investigate the order and the strength of the transition at large Nc. We also report on our determination of the criti...
متن کاملThe SU(3) deconfining phase transition with Symanzik action
We report on the determination of the deconfining temperature in SU(3) pure gauge theory, using the Symanzik tree level improved action, on lattices of size 3× 12, 4× 16, 5× 20, 6× 24. We find that the asymptotic scaling violation pattern is similar to the one observed using the Wilson action. We conclude that the irrelevant operators do not affect, in the range of couplings considered, the lat...
متن کاملNature of the deconfining phase transition in the 2+1-dimensional SU(N) Georgi-Glashow model
The nature of the deconfining phase transition in the 2+1-dimensional SU(N) GeorgiGlashow model is investigated. Within the dimensional-reduction hypothesis, the properties of the transition are described by a two-dimensional vectorial Coulomb gas models of electric and magnetic charges. The resulting critical properties are governed by a generalized SU(N) sine-Gordon model with self-dual symme...
متن کاملRenormalized Polyakov Loops, Matrix Models and the Gross-witten Point
The values of renormalized Polyakov loops in the three lowest representations of SU(3) were measured numerically on the lattice. We find that in magnitude, condensates respect the large-N property of factorization. In several ways, the deconfining phase transition for N = 3 appears to be like that in the N = ∞ matrix model of Gross and Witten. Surprisingly, we find that the values of the renorm...
