论文摘要
高度沮丧的旋转系统（例如Kagome晶格（KL））是具有较大纠缠的新量子状态的宝库。因此，我们使用密度 - 矩阵肾化统计组（DMRG）方法研究了Kagome-Strip链（KSC）上的自旋 - $ \ frac {1} {2} $ Heisenberg模型，该模型是一维KL。计算KSC的中央电荷和纠缠光谱，我们在1/5磁化高原中找到了一种新型的无缝隙液态，并具有双重变性的纠缠光谱。我们还在通过动态DMRG方法计算的动态自旋结构中获得了无间隙的低洼连续性。我们提出了一个符合这些功能的谐音二聚体液态状态。
Highly frustrated spin systems such as the kagome lattice (KL) are a treasure trove of new quantum states with large entanglements. We thus study the spin-$\frac{1}{2}$ Heisenberg model on a kagome-strip chain (KSC), which is one-dimensional KL, using the density-matrix renormalization group (DMRG) method. Calculating central charge and entanglement spectrum for the KSC, we find a novel gapless spin liquid state with doubly degenerate entanglement spectra in a 1/5 magnetization plateau. We also obtain a gapless low-lying continuum in the dynamic spin structure calculated by dynamical DMRG method. We propose a resonating dimer-monomer liquid state that would meet these features.
