论文摘要
我们报告了未铺设的正方形晶格阵列中相互作用的Rydberg原子的基态相图。使用新的张量网络算法，我们在两个维度上扩展到大型系统，同时包括所有远程相互作用，从而揭示了散装中的相位及其在可访问的有限阵列中的类似物。我们发现了早期的数值和实验研究的相图发生了很大变化，尤其是我们发现了出现在没有挫败感的情况下出现的新出现的纠缠量子列相。从广义上讲，我们的结果为将来的实验提供了概念指南，而我们的技术为其他晶格的数值研究提供了蓝图。
We report on the ground state phase diagram of interacting Rydberg atoms in the unfrustrated square lattice array. Using new tensor network algorithms, we scale to large systems in two dimensions while including all long-range interactions, revealing the phases in the bulk and their analogs in accessible finite arrays. We find a greatly altered phase diagram from earlier numerical and experimental studies, and in particular, we uncover an emergent entangled quantum nematic phase that appears in the absence of frustration. Broadly our results yield a conceptual guide for future experiments, while our techniques provide a blueprint for converging numerical studies in other lattices.
