论文摘要
我们讨论了基于投影操作员方法的广义哈伯德模型的确切固定基态，用于几个角落共享晶格：kagome，checherboard和pyrochlore lattices。所获得的精确接地状态被解释为在斑块上的电子上的néel有序状态。我们证明这些模型也具有精确的边缘状态。我们还精确地计算了这些系统中的纠缠熵。
We discuss exact plaquette-ordered ground states of the generalized Hubbard model based on the projection operator method for several corner sharing lattices: Kagome, checkerboard, and pyrochlore lattices. The obtained exact ground states are interpreted as Néel ordered states on the plaquette-located electrons. We demonstrate that these models also have exact edge states. We also calculate the entanglement entropy exactly in these systems.
