论文摘要
在$ n = 3/4 $填充Moiré平面乐队时，过渡金属二进制基因元素化MoiréBiLayers将开发Kagome充电订单。我们为所得的局部旋转得出了一个有效的自旋模型，发现其进一步的邻居自旋相互作用可能比相应的电子跳高强度所抑制得多。使用密度矩阵重新归一化组模拟，我们研究其相图，对于与WSE $ _2 $/WS $ _2 $相关的现实模型参数，我们表明该材料可以实现异国情调的手性旋转液相和高度争议的Kagome旋转液体。因此，我们的工作表明，TMD Heterobilayers中存在的挫败感和强烈的相互作用为研究旋转液体物理学提供了令人兴奋的平台。
At $n=3/4$ filling of the moiré flat band, transition metal dichalcogenide moiré bilayers will develop kagome charge order. We derive an effective spin model for the resulting localized spins and find that its further neighbor spin interactions can be much less suppressed than the corresponding electron hopping strength. Using density matrix renormalization group simulations, we study its phase diagram and, for realistic model parameters relevant for WSe$_2$/WS$_2$, we show that this material can realize the exotic chiral spin liquid phase and the highly debated kagome spin liquid. Our work thus demonstrates that the frustration and strong interactions present in TMD heterobilayers provide an exciting platform to study spin liquid physics.
