论文摘要
我们报告了在装饰蜂窝晶状体上的单门哈伯德模型中引起的十个基础状态。包括Dirac Metals，Flat Band Ferromagnets，真实空间的Mott绝缘子，二聚体和Trimer Mott绝缘子，以及旋转$ 1 $ $ 1 $ MOTT的绝缘子。丰富的相图来自单位电池内的结构。因此，这种状态在较简单的晶格上不存在。我们认为，这种绝缘阶段在装饰的格子上很普遍。这些在许多材料中都可以找到，并且在协调聚合物中常见，提供了一个探索物理学的操场。
We report ten ground states arising from strong correlations in the single-orbital Hubbard model on the decorated honeycomb lattice; including Dirac metals, flat-band ferromagnets, real-space Mott insulators, dimer and trimer Mott insulators, and a spin-$1$ Mott insulator. The rich phase diagram arises from structures within the unit cell. Hence, such states are absent on simpler lattices. We argue that such insulating phases are prevalent on decorated lattices. These are found in many materials and common in coordination polymers, providing a playground to explore this physics.
