Vanden Broeck 和 Schwartz 提出的序列变换方法用于加速基态能量数值有限格数据收敛到无限格极限。对 S= 1 2 反铁磁海森堡和 XY 环的基态能量进行了高度准确的估计。 S=1 反铁磁海森堡环的基态能量也被准确估计。
The sequence-transformation method due to Vanden Broeck and Schwartz is used to accelerate the convergence of numerical finite-lattice data on ground-state energies to their infinite-lattice limit. Highly accurate estimates of the ground-state energy are obtained for the S= 1 2 antiferromagnetic Heisenberg and XY rings. The ground-state energy of the S= 1 antiferromagnetic Heisenberg ring is also estimated accurately.
