Variational Monte Carlo (VMC) studies of extended Kitaev honeycomb models reveal a series of multinode quantum spin liquids (QSLs). They have an emergent Z2 gauge structure, a discrete number of symmetry-protected Majorana cones, and form Abelian or non-Abelian chiral spin liquids in applied magnetic fields. The large number of Z2 projective symmetry groups for spin–orbit-coupled states on the honeycomb lattice suggests that multinode QSLs can be found experimentally in future work on proximate Kitaev materials.

扩展 Kitaev 蜂窝模型中的多节点量子自旋液体
扩展 Kitaev 蜂窝模型的变分蒙特卡洛 (VMC) 研究揭示了一系列多节点量子自旋液体 (QSL)。它们具有新兴的 Z2 规范结构、离散数量的对称保护 Majorana 锥,并在外加磁场中形成阿贝尔或非阿贝尔手性自旋液体。蜂窝晶格上用于自旋-轨道耦合态的大量 Z2 射影对称群表明,在未来对近似 Kitaev 材料的研究中,可以在实验中找到多节点 QSL。
