Oleg Borisenko, Volodymyr Chelnokov, Mario Gravina, Alessandro Papa

摘要:

本文在对偶形式下研究了有限温度下的三维U(1)格点规范理论。对于适当的无序算符,我们得到了描述模型在退禁闭相变附近临界行为的重整化群方程。这些方程被用来检验Svetitsky-Yaffe猜想关于格点U(1)模型临界行为的有效性。此外,我们进行了数值模拟的模型$N_t = 1, 2, 4, 8$和计算,通过聚类算法,双关联函数和相应的二阶矩相关长度。用这种方法确定了临界点的位置,计算了临界指数。

英文摘要:

We study analytically and numerically the three-dimensional U(1) lattice gauge theory at finite temperature in the dual formulation. For an appropriate disorder operator, we obtain the renormalization group equations describing the critical behavior of the model in the vicinity of the deconfinement phase transition. These equations are used to check the validity of the Svetitsky-Yaffe conjecture regarding the critical behavior of the lattice U(1) model. Furthermore, we perform numerical simulations of the model for $N_t = 1, 2, 4, 8$ and compute, by a cluster algorithm, the dual correlation functions and the corresponding second moment correlation length. In this way we locate the position of the critical point and calculate critical indices.
