Coherent center domains from local Polyakov loops

摘要:

我们分析了本地Polyakov环的性质,淬火以及动力学SU(3)规范配置在很宽的温度范围内。它表明,无论是限制和解除限制制度,当地的Polyakov环更喜欢的中心元素1,exp(i 2 π/3),exp(-i 2 π/3)附近的相位值。根据这些阶段,我们将晶格位置分为三个部门,并表明部门引起的集群的形成。对于这些集群的一个合适的定义,我们发现,在淬火的情况下,解除禁闭表现为开始的集群的渗流。一个可能的连续极限的中心集群进行了讨论。

英文摘要:

We analyze properties of local Polyakov loops using quenched as well as dynamical SU(3) gauge configurations for a wide range of temperatures. It is demonstrated that for both, the confined and the deconfined regime, the local Polyakov loop prefers phase values near the center elements 1, exp(i 2 pi/3), exp(-i 2 pi/3). We divide the lattice sites into three sectors according to these phases and show that the sectors give rise to the formation of clusters. For a suitable definition of these clusters we find that in the quenched case deconfinement manifests itself as the onset of percolation of the clusters. A possible continuum limit of the center clusters is discussed.
