摘要

用计算物理方法研究了Kagome晶格上装饰Ising模型的基态。该模型考虑了最近节点邻居之间、次近邻节点邻居之间以及节点与最近装饰邻居之间的交换相互作用。根据节点自旋与装饰自旋之间以及节点自旋本身之间的交换相互作用的不同比例，确定了基态构型。确定了具有不同基态构型的区域存在的边界。计算了所有构型的基态能值。

Ground state of the decorated Ising model on the Kagome lattice

The ground state of the decorated Ising model on the Kagome lattice is studied using computational physics methods. The model takes into account the exchange interactions between the nearest nodal neighbors, next-to-nearest nodal neighbors, and between nodal and nearest decorated neighbors. The ground state configurations are determined for various ratios of the exchange interactions between nodal spins and decorated spins, as well as between nodal spins themselves. The boundaries for the existence of regions with different ground state configurations are determined. The ground state energy values are calculated for all configurations.
