标题： Tensor renormalization group study of the non-Abelian Higgs model in two dimensions

摘要： 我们使用张量重正化群（TRG）方法研究二维欧几里得空间中的$SU(2)$规范-希格斯模型。 我们在单位规范下为该模型推导出一种张量表述，并将不同可观测量的期望值与TRG和蒙特卡洛模拟进行比较，发现两种方法之间有很好的一致性。 实际上我们发现TRG方法在计算用于提取静态夸克势的普拉科夫环相关函数方面远优于蒙特卡洛模拟。 显示英文摘要

摘要： We study the $SU(2)$ gauge-Higgs model in two Euclidean dimensions using the tensor renormalization group (TRG) approach. We derive a tensor formulation for this model in the unitary gauge and compare the expectation values of different observables between TRG and Monte Carlo simulations finding excellent agreement between the two methods. In practice we find the TRG method to be far superior to Monte Carlo simulation for calculations of the Polyakov loop correlation function which is used to extract the static quark potential.
