论文摘要
在这项工作中,我们在一维自旋 - $ s $ kitaev-heisenberg-gamma模型中进行了经典和自旋波分析的组合。 Four phases are found, including a Néel ordered phase, a phase with $O_h\rightarrow D_3$ symmetry breaking, and "$D_3$-breaking I, II" phases which both break $D_3$ symmetries albeit in different ways, where $O_h$ is the full octahedral group and $D_3$ is the dihedral group of order six.最低的自旋波质量是在隐藏的SU(2)对称铁磁点附近触及扰动的。
In this work, we perform a combination of classical and spin wave analysis on the one-dimensional spin-$S$ Kitaev-Heisenberg-Gamma model in the region of an antiferromagnetic Kitaev coupling. Four phases are found, including a Néel ordered phase, a phase with $O_h\rightarrow D_3$ symmetry breaking, and "$D_3$-breaking I, II" phases which both break $D_3$ symmetries albeit in different ways, where $O_h$ is the full octahedral group and $D_3$ is the dihedral group of order six. The lowest-lying spin wave mass is calculated perturbatively in the vicinity of the hidden SU(2) symmetric ferromagnetic point.
