Spin systems with frustrated anisotropic interactions are of significant interest due to possible exotic ground states. We have explored their phase diagram on a nearest-neighbor triangular lattice using the density-matrix renormalization group and mapped out the topography of the region that can harbor a spin liquid. We find that this spin-liquid phase is continuously connected to a previously discovered spin-liquid phase of the isotropic J_{1}-J_{2} model. The two limits show nearly identical spin correlations, making the case that their respective spin liquids are isomorphic to each other.
具有各向异性 frustrated 相互作用的自旋系统因其可能存在奇特的基态而备受关注。我们使用密度矩阵重整化群研究了最近邻三角晶格上的相图,并绘制了可能存在自旋液体的区域地形。我们发现,这个自旋液体相与之前发现的各向同性 J1-J2 模型的自旋液体相连续相连。这两个极限的自旋关联几乎完全相同,表明它们各自的自旋液体是同构的。
