三角晶格上自旋液体与自旋轨道的耦合

Spin Liquid versus Spin Orbit Coupling on the Triangular Lattice

Jason Iaconis, Chunxiao Liu, Gábor B. Halász, Leon Balents

摘要:

本文探讨了强自旋轨道耦合与自旋液体物理的关系。我们研究了一个非常一般的模型上的三角晶格自旋轨道耦合导致高度各向异性的相互作用的存在。通过Gutzwiller投影的费米子构造,我们用变分蒙特卡罗方法研究了$U(1)$量子自旋液体态和有序态。从而得到了该相空间中的基态相图。此外,我们考虑自旋费米表面量子自旋液体,这是特别重要的自旋轨道耦合时,Gutzwiller波函数以外的影响。

英文摘要:

In this paper, we explore the relationship between strong spin-orbit coupling and spin liquid physics. We study a very general model on the triangular lattice where spin-orbit coupling leads to the presence of highly anisotropic interactions. We use variational Monte Carlo to study both $U(1)$ quantum spin liquid states and ordered ones, via the Gutzwiller projected fermion construction. We thereby obtain the ground state phase diagram in this phase space. We furthermore consider effects beyond the Gutzwiller wavefunctions for the spinon Fermi surface quantum spin liquid, which are of particular importance when spin-orbit coupling is present.
