论文摘要
我们通过经典和量子模拟的组合研究了与材料相关的参数状态中蜂窝基塔维 - $γ$模型的基础性质。经典模型印有高度结构化的自旋双螺旋的缠结。该螺旋缠结表现出$ 18 $不相等的螺旋轴，并具有自发周期性各向异性和$ {\ rm sgn}（γ）$ - 确定的手性手性模式。 Infinite Peps模拟，簇$ 36 $站点以量子旋转$ 1/2 $型号确定了此多体订单的标志。我们的发现提供了Kitaev- $γ$模型的新观点，并丰富了Kitaev磁性的物理学。
We investigate the ground-state nature of the honeycomb Kitaev-$Γ$ model in the material-relevant parameter regime through a combination of classical and quantum simulations. The classical model is imprinted with a tangle of highly structured spin double helices. This helix tangle exhibits $18$ inequivalent helical axes and features a spontaneous periodicity anisotropy and a ${\rm sgn}(Γ)$-determined chirality pattern. Infinite PEPS simulations with clusters up to $36$ sites identify hallmarks of this many-body order in the quantum spin-$1/2$ model. Our findings provide a fresh perspective of the Kitaev-$Γ$ model and enrich the physics of Kitaev magnetism.
