摘要
本文讨论了开边界条件下自旋1/2 Heisenberg XXZ 模型的潜藏定域规范不变性.结果表明,尽管模型Hamiltonian 量及其本征矢明显规范相关,但其能量本征值和Bethe 方程却是规范不变的.
Hidden local gauge invariance in spin-(1/2)quantum Heicsenberg XXZ moddel under open boundary conditions isstudied in the frame work of quantum inverse scattering method(QISM).Our results show that the Hamiltionianand its eigenvectors are explicitly gauge-dependent while the energy eigenvalues and the Bethe equations are gauge-invariant.
