理论与实验物理研究所，B。Cheremushkinskaya 25，莫斯科117259，Russia在平衡状态下，在低于和高于去离子相变的有限温度下，我们产生了格点SU（2）规范场，并将它们暴露于涂抹，以研究新兴的拓扑电荷簇。根据最大阿贝尔规范分析了这些团簇，我们已经能够在具有非平凡完整性的Kraan-van Baal caloron解的上下文中描述部分拓扑团簇对应于非静态caloron或静态dyons。我们发现这些calorons和dyons的相对丰度随温度而变化，并解释为calorons分解成dyons随温度的升高。拓扑簇内的Polyakov环的轮廓和（依赖于模型的）累积拓扑簇电荷支持这种解释。在去纠缠相变之上，轻双子（根据几乎平凡的完整性的Kraan-van Baal caloron解）成为最丰富的拓扑对象。它们大概是负责在deconfined阶段的磁confinement。
Institute for Theoretical and Experimental Physics,B. Cheremushkinskaya 25, Moscow 117259, RussiaIn equilibrium, at finite temperature below and above the deconfining phase transition, we havegenerated lattice SU(2) gauge fields and have exposed them to smearing in order to investigate theemerging clusters of topological charge. Analysing in addition the monopole clusters according tothe maximally Abelian gauge, we have been able to characterize part of the topological clusters tocorrespond either to non-static calorons or static dyons in the context of Kraan-van Baal caloronsolutions with non-trivial holonomy. We show that the relative abundance of these calorons anddyons is changing with temperature and offer an interpretation as dissociation of calorons into dyonswith increasing temperature. The profile of the Polyakov loop inside the topological clusters and the(model-dependent) accumulated topological cluster charges support this interpretation. Above thedeconfining phase transition light dyons (according to Kraan-van Baal caloron solutions with almosttrivial holonomy) become the most abundant topological objects. They are presumably responsiblefor the magnetic confinement in the deconfined phase.
