论文摘要
离散空间量子系统求解器（DSQSS）是一个程序包，用于解决晶格定义的量子多体问题。 DSQS基于Feynman的路径积分表示中的量子蒙特卡洛法，并使用灵活的输入文件涵盖了广泛的问题，这些柔性输入文件在任意维度和任意矩阵元素中定义了任意矩阵元素，代表了自由度的任意数量之间的相互作用。可以通过指定参数（例如尺寸，晶格大小，耦合常数和温度）来执行量子自旋和Bose-Hubbard模型的有限温度计算。本文详细介绍了DSQSS的使用，并提供了许多应用程序。
The Discrete Space Quantum Systems Solver (DSQSS) is a program package for solving quantum many-body problems defined on lattices. The DSQSS is based on the quantum Monte Carlo method in Feynman's path integral representation and covers a broad range of problems using flexible input files that define arbitrary unit cells in arbitrary dimensions and arbitrary matrix elements representing the interactions among an arbitrary number of degrees of freedom. Finite temperature calculations of quantum spin and the Bose- Hubbard models can be performed by specifying parameters such as the number of dimensions, the lattice size, coupling constants, and temperature. The present paper details the use of DSQSS and presents a number of applications thereof.
