| Abstract: | 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. |
