Judah Unmuth-Yockey, Jin Zhang, Alexei Bazavov, Yannick Meurice, Shan-Wen Tsai

摘要:

我们证明了二维格点阿贝尔Higgs模型的Polyakov环可以用张量重整化群方法计算。我们使用标准的蒙特卡罗模拟检查结果的准确性。我们表明,插入的Polyakov环产生的能隙服从普遍的有限尺寸标度,持续在时间连续极限。我们简要地讨论了这些结果的相关性量子模拟。

英文摘要:

We show that the Polyakov loop of the two-dimensional lattice Abelian Higgs model can be calculated using the tensor renormalization group approach. We check the accuracy of the results using standard Monte Carlo simulations. We show that the energy gap produced by the insertion of the Polyakov loop obeys universal finite-size scaling which persists in the time continuum limit. We briefly discuss the relevance of these results for quantum simulations.
