Abstract

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.

扩展基塔耶夫蜂巢模型中的多节点量子自旋液体
对扩展基塔耶夫蜂窝模型的变分蒙特卡罗(VMC)研究揭示了一系列多节点量子自旋液体(QSL)。它们具有新出现的 Z2 计结构、离散数量的对称保护马约拉纳锥,并在外加磁场中形成阿贝尔或非阿贝尔手性自旋液体。蜂巢晶格上自旋轨道耦合态的大量 Z2 投射对称群表明,在未来关于近似基塔耶夫材料的工作中,可以在实验中发现多节点 QSL。
