资源简介：
We present a high-temperature series expansion code for spin-1/2 Heisenberg models on arbitrary lattices. As an example we demonstrate how to use the application for an anisotropic triangular lattice with two independent couplings J1 and J2 and calculate the high-temperature series of the magnetic susceptibility and the static structure factor up to 12th and 10th order, respectively. We show how to extract effective coupling constants for the triangular Heisenberg model from experimental data on Cs2CuBr4.
本报告呈现了一款适用于任意晶格上自旋1/2海森堡模型的低温级数展开代码。以各向异性的三角形晶格为例，我们展示了如何运用该应用进行计算，并分别计算了磁化率的高温级数至12阶以及静态结构因子至10阶。此外，我们还阐述了如何从Cs2CuBr4的实验数据中提取三角形海森堡模型的有效耦合常数。（spin-1/2 Heisenberg models, anisotropic triangular lattice, couplings J1 and J2, magnetic susceptibility, static structure factor）
