论文摘要
我们证明，单个孔的运动在$ u = \ u = \ undty $ hubbard模型上引起最近的邻元谐振 - 价值基键状态，这是三角形仙人掌 - kagome lattice的树状变体。结果很容易将其推广到具有抗磁相互作用的$ t-j $模型，同一图上的$ j \ geq 0 $。这是Nagaoka在两部分晶格上的铁磁性定理的薄弱。
We prove that the motion of a single hole induces the nearest-neighbor resonating-valence-bond ground state in the $U=\infty$ Hubbard model on a triangular cactus - a tree-like variant of a kagome lattice. The result can be easily generalized to $t-J$ models with antiferromagnetic interactions $J\geq 0$ on the same graphs. This is a weak converse of Nagaoka's theorem of ferromagnetism on a bipartite lattice.
