High temperature expansion via Schwinger-Dyson equations: The planar rotator model on a triangular lattice

Title of program: KAPPA,KP Catalogue Id: AATS_v1_0 Nature of problem We describe a Fortran program implementing a new algorithm to compute high temperature expansions for lattice spin models. The case of the planar rotator model on a triangular lattice is illustrated here in detail. Versions of this program held in the CPC repository in Mendeley Data AATS_v1_0; KAPPA,KP; 10.1016/0010-4655(87)90024-5 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)程序名称：KAPPA、KP 目录编号：AATS_v1_0 问题概述：本文介绍一款Fortran程序，该程序实现了用于计算晶格自旋模型高温展开的全新算法。本文以三角晶格上的平面转子模型为例，对该算法的应用进行了详细演示。 存放在曼德莱数据（Mendeley Data）的CPC库中的该程序相关信息：AATS_v1_0；KAPPA、KP；10.1016/0010-4655(87)90024-5 本程序源自贝尔法斯特女王大学托管的CPC程序库（1969-2018年）
