| 摘 要： | 详细研究了自旋为1的Heisenberg XXZ模型(Fateev-Zamolodchikov模型)的潜藏定域规范不变性。发现与自旋为1/2的情形相类似,该模型允许AbelU(1)规范交换,且其能谱在规范变换下保持不变,而其本征矢却与规范变换明显相关。

| Abstract: | Hidden local gauge invariance in Fateev-Zamolodchikov quantum spin chain is studied in detail in the framework of the quantum inverse scattering method (QISM). It is found that, similar to the case of spin 1/2, this model admits an Abelian U(1) gauge transformation and that the energy spectrum is gauge invariant whereas the eigenvectors are explicitly gauge dependent. |
