论文摘要
我们研究了在SPIN-1/2 XXZ模型的强耦合极限下，在中间时间尺度上的有效的哈密顿生成时间演变。为了指导顺序，它描述了具有本地交互的可集成模型。我们通过明显打破翻译对称性的坐标坐标来完全解决它。我们证明了许多被困住的国家的存在，并在有效的哈密顿人的领先纠正下估计了它们的稳定性。讨论了模型的一些基态特性。
We study an effective Hamiltonian generating time evolution of states on intermediate time scales in the strong-coupling limit of the spin-1/2 XXZ model. To leading order, it describes an integrable model with local interactions. We solve it completely by means of a coordinate Bethe Ansatz that manifestly breaks the translational symmetry. We demonstrate the existence of exponentially many jammed states and estimate their stability under the leading correction to the effective Hamiltonian. Some ground state properties of the model are discussed.
