论文摘要
Kitaev Honeycomb模型中的Loudon-Fleury非弹性可见光散射的完美脱落是众所周知的。尽管它也发生在海森贝格·卡戈姆（Heisenberg Kagome）和三角形抗铁磁铁中，但我们证明它具有几何起源，而不是量子自旋液体的特殊性。 A Kitaev spin liquid in the square planar geometry indeed exhibits polarized Raman spectra containing defferent symmetry species, each brought by symmetry-compatible spinon geminate excitations, i.e. arising from symmetry-compatible direct-product representations made of double-valued irreducible representations of mediating-spinon-belonging gauged $\bm{k}$-point symmetry groups.我们结合了对真实空间中拉曼顶点的标准点对称组分析，以及对倒数空间中拉曼 - 散散制的主要旋转子的精心射击射击对称组分析，以单独识别出现的蜘蛛。
Perfect deporalization of the Loudon-Fleury inelastic visible-light scattering in the Kitaev honeycomb model is well known. Though it happens in Heisenberg Kagome and triangular antiferromagnets as well, yet we prove it to be of geometric origin rather than peculiar to quantum spin liquids. A Kitaev spin liquid in the square planar geometry indeed exhibits polarized Raman spectra containing defferent symmetry species, each brought by symmetry-compatible spinon geminate excitations, i.e. arising from symmetry-compatible direct-product representations made of double-valued irreducible representations of mediating-spinon-belonging gauged $\bm{k}$-point symmetry groups. We combine a standard point-symmetry-group analysis of the Raman vertex in the real space and an elaborate projective-symmetry-group analysis of Raman-scattering-mediating Majorana spinons in the reciprocal space to identify emergent spinons singly.
