论文摘要
我们通过数值晶格模拟来研究重新构造相变的特性,发生在痕量变形$ su(3)$ yang-mills理论中,在$ \ mathbb {r}^3 \ times s^1 $上定义,即使在小压缩radii中也恢复了中心对称性。我们通过有限的尺寸缩放分析表明,重新结合相变是一阶,就像通常的$ su(3)$热相变。然后,我们研究了两种不同的物理现象,这些现象已知,这些现象是表征标准限制/解剖相变的特征,即热磁单波的凝结以及狄拉克操作员特征型的定位特性的变化。关于后者,我们表明,随着进入重新固定的相位,dirac频谱中类似安德森的跃迁的移动性边缘会消失,因为它发生在标准限制阶段中。相反,热单孔显示出一种特殊的行为:它们的密度与标准热理论一致性下降。尽管如此,它们还是在重新融资时浓缩,就像通常的监禁过渡一样。即使在与标准限制过渡的框架不同的框架中,单极凝结和狄拉克模式的巧合也表明它们之间存在严格的联系。
We study, by means of numerical lattice simulations, the properties of the reconfinement phase transition taking place in trace deformed $SU(3)$ Yang-Mills theory defined on $\mathbb{R}^3\times S^1$, in which center symmetry is recovered even for small compactification radii. We show, by means of a finite size scaling analysis, that the reconfinement phase transition is first-order, like the usual $SU(3)$ thermal phase transition. We then investigate two different physical phenomena, which are known to characterize the standard confinement/deconfinement phase transition, namely the condensation of thermal magnetic monopoles and the change in the localization properties of the eigenmodes of the Dirac operator. Regarding the latter, we show that the mobility edge signalling the Anderson-like transition in the Dirac spectrum vanishes as one enters the reconfined phase, as it happens in the standard confined phase. Thermal monopoles, instead, show a peculiar behavior: their density decreases going through reconfinement, at odds with the standard thermal theory; nonetheless, they condense at reconfinement, like at the usual confinement transition. The coincidence of monopole condensation and Dirac mode delocalization, even in a framework different from that of the standard confinement transition, suggests the existence of a strict link between them.
