论文摘要
我们将张量重新归一化组方法应用于有限化学势的（1+1）二维SU（2）主手性模型，并使用高斯 - legendre正交正交正交分离su（2）lie ofter。化学势$μ= 0 $的内部能量与强耦合膨胀的预测表现出良好的一致性。这表明高斯 - legendre正交对su（2）谎言组的分区的有效性。在有限密度区域中，在强耦合下，我们观察到了数字密度的银燃料现象。
We apply the tensor renormalization group method to the (1+1)-dimensional SU(2) principal chiral model at finite chemical potential with the use of the Gauss-Legendre quadrature to discretize the SU(2) Lie group. The internal energy at vanishing chemical potential $μ=0$ shows good consistency with the prediction of the strong and weak coupling expansions. This indicates an effectiveness of the Gauss-Legendre quadrature for the partitioning of the SU(2) Lie group. In the finite density region with $μ\ne 0$ at the strong coupling we observe the Silver-Blaze phenomenon for the number density.
