论文摘要
我们使用集群扩展来建立有限体积基接地状态的本地固定性，用于AKLT模型，用于装饰的具有装饰参数的装饰的六角形晶格至少5个。我们的估计意味着该模型满足本地拓扑量子订单（LTQO），因此在基础状态上方的光谱差距稳定在本地扰动上。
We use cluster expansions to establish local indistiguishability of the finite-volume ground states for the AKLT model on decorated hexagonal lattices with decoration parameter at least 5. Our estimates imply that the model satisfies local topological quantum order (LTQO), and so the spectral gap above the ground state is stable against local perturbations.
