量子二聚体模型是已知的主机拓扑量子自旋液相，它最近已经成为可能模拟这样的模型与里德堡原子被困在光镊阵列。在这里，我们提出了大规模的量子Monte Carlo模拟结果的扩展的三角晶格量子二聚体模型的哈密顿湮没和创建单一的二聚体。我们发现不同的奇数和偶数自旋液体，沿着与几个阶段没有拓扑秩序：交错晶体，一个非对称相，和一个平凡的对称相没有明显的对称性破缺。我们还提出了动态光谱的阶段，并注意到里德堡原子的实验的影响。量子二聚体模型是已知的主机拓扑量子自旋液相，它最近已经成为可能模拟相关规范理论与里德伯原子。Yan等人计算了实验激发的量子二聚体模型在具有波动二聚体密度的三角晶格上的相图。
Quantum dimer models are known to host topological quantum spin liquid phases, and it has recently become possible to simulate such models with Rydberg atoms trapped in arrays of optical tweezers. Here, we present large-scale quantum Monte Carlo simulation results on an extension of the triangular lattice quantum dimer model with terms in the Hamiltonian annihilating and creating single dimers. We find distinct odd and even spin liquids, along with several phases with no topological order: a staggered crystal, a nematic phase, and a trivial symmetric phase with no obvious broken symmetry. We also present dynamic spectra of the phases, and note implications for experiments on Rydberg atoms. Quantum dimer models are known to host topological quantum spin liquid phases, and it has recently become possible to simulate related gauge theories with Rydberg atoms. Yan et al. compute the phase diagram of an experimentally motivated quantum dimer model on a triangular lattice with fluctuating dimer density.
