我们研究了双夸克凝聚作为QCD禁闭-去禁闭相变的信号。最近，Bilgici等人定义了中心对称性的序参数。在晶格QCD的框架内。在这项工作中，我们利用环面上夸克传播子的Dyson-Schwinger方程的形式，用泛函方法确定了普通夸克凝聚体和双夸克凝聚体。这些凝聚体的温度依赖性用于研究猝灭QCD的手征跃迁和退禁闭跃迁之间的相互作用。
We study the dual quark condensate as a signal for the confinement-deconfinement phase transition of QCD. This order parameter for center symmetry has been defined recently by Bilgici et al. within the framework of lattice QCD. In this work we determine the ordinary and the dual quark condensate with functional methods using a formulation of the Dyson-Schwinger equations for the quark propagator on a torus. The temperature dependence of these condensates serves to investigate the interplay between the chiral and deconfinement transitions of quenched QCD.
