论文摘要
我们在Kagome晶格上介绍了一类量子二聚体模型，具有完整的翻译不变性，这些不变性具有量子多体疤痕状态，其光谱中具有分析已知的纠缠属性。使用在高达60个位点的晶格上使用精确的对角度化，我们表明非标准状态符合本征态热化假设。具体而言，我们表明能量是根据其各自的对称部门的高斯集合的分布的，说明了两部分纠缠特性的疤痕的存在，并在保真度动力学研究中证明了复兴现象。
We present a class of quantum dimer models on the kagome lattice with full translational invariance that feature a quantum many-body scar state of analytically known entanglement properties within their spectra. Using exact diagonalization on lattices of up to 60 sites, we show that non-scar states conform to the eigenstate thermalization hypothesis. Specifically, we show that energies are distributed according to the Gaussian ensemble expected of their respective symmetry sector, illustrate the existence of the scar from bipartite entanglement properties, and demonstrate revival phenomena in studies of fidelity dynamics.
