论文摘要
在这项工作中，我们分析了各种具有粘结交替的广义的Kitaev旋转链和梯子的非词形对称组结构，包括Kitaev-Gamma链，Kitaev-Heisenberg-Gamma链，除了最近的邻居相互作用，以及两与腿的spinders。对称分析用于确定键 - 隔离的Kitaev-Gamma旋转链中几个磁性相的对称性破坏模式，以及自发二聚体的二聚化顺序参数。我们的工作对于理解相关模型中的磁相很有用，并且可以在进一步研究中为平均场解决方案的对称分类提供指导。
In this work, we analyze the nonsymmorphic symmetry group structures for a variety of generalized Kitaev spin chains and ladders with bond alternations, including Kitaev-Gamma chain, Kitaev-Heisenberg-Gamma chain, beyond nearest neighbor interactions, and two-leg spin ladders. The symmetry analysis is applied to determine the symmetry breaking patterns of several magnetically ordered phases in the bond-alternating Kitaev-Gamma spin chains, as well as the dimerization order parameters for spontaneous dimerizations. Our work is useful in understanding the magnetic phases in related models and may provide guidance for the symmetry classifications of mean field solutions in further investigations.
