Abstract

Hidden local gauge invariance for Osp (2,1) spin chain is studied in the frame work of the quantum inverse scattering method. It is found that this model admits an Abel U (1) gauge transformation and the energy spectrum is gauge invariant, where as the eigenvectors and Be the an satz equations are explicitly gauge dependent.

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.

Hidden local gauge invariance in Fatteev-Zamolodchikov quantum spin chain under open bondary conditions is studied in the framework of quantum inverse scattering method (QISM). Our results show that the Hamiltonian and its eigenvectors are explicitly gauge-dependent while the energy eigenvalues and the Bethe equations are gauge-invariant.

Hidden local gauge invariance in the one-dimensional Hubbard model and its equivalent coupled spin model

Huan-Qiang Zhou, Lin-Jie Jiang, Ping‐Feng Wu

Hidden local gauge invariance in the one-dimensional (1-D) Hubbard model and its equivalent coupled spin model is studied. It is found that Abelian U(1)⊗U(1) gauge transformations appear in both cases. Furthermore, it is shown that the energy spectrum is gauge invariant whereas the eigenvectors are explicitly gauge dependent. However, this result relies heavily on Shastry’s conjecture about the eigenvalue of the transfer matrix for the 1-D Hubbard model. Lastly, there is also a discrete symmetry associated to Z2⊗Z2. Once this symmetry is broken, one immediately obtains another nontrivial solution to the Yang–Baxter relations. UFaipxr

Hidden local gauge invariance in the one-dimensional Heisenberg XXZ model with the general boundary terms

Huan-Qiang Zhou, Xi‐Wen Guan

Hidden local gauge invariance in the one-dimensional Heisenberg XXZ model with the general boundary terms is studied in the framework of the quantum inverse scattering method. The Bethe ansatz equations are established for the model with the special boundary terms. Our results show that the Hamiltonian and its eigenvectors are explicitly gauge dependent whereas the energy eigenvalues and the Bethe ansatz equations are gauge invariant.

A method for solving the equation of a ferromagnetic chain and verification of the Takhtajan equation

Huang Nianning

Based on the gauge equivalence, we solve the equation of a Heisenberg ferromagnetic chain by using the inverse scattering method of the nonlinear Schrodinger equation and an explicitly obtained form of the required gauge transformation. We show that the solutions of a ferromagnetic chain by the Takhtajan's method identify with that by the above mentioned method. Then we prove the correctness of the Takhtajan equation and avoid the defects in its derivations.
