论文摘要
Sierpiński金字塔上的两态量子POTTS模型的相变,通过张量网络框架(高阶张量重量化组方法)研究。评估了横向磁场和磁指数$β$的临界值。尽管Sierpiński金字塔的Hausdorff尺寸正好是两个$(= \ log_2^{〜} 4)$,但获得的关键属性表明,有效尺寸低于两个。
Phase transition of the two- and three-state quantum Potts models on the Sierpiński pyramid are studied by means of a tensor network framework, the higher-order tensor renormalization group method. Critical values of the transverse magnetic field and the magnetic exponent $β$ are evaluated. Despite the fact that the Hausdorff dimension of the Sierpiński pyramid is exactly two $( = \log_2^{~} 4)$, the obtained critical properties show that the effective dimension is lower than two.
