摘要
首先对路径积分蒙特卡罗(PIMC)方法的基本原理进行详细介绍,重点综述该方法处理费米系统的手段。然后对PIMC方法在计算多种体系的状态方程所取得的成果进行总结比较,分析该方法的优点与不足。最后对PIMC方法未来的发展方向做出展望。
In this paper,the basic framework of PIMC method is firstly described in detail.In particular,four techniques developed for PIMC simulations to deal with the Fermi sign problem are reviewed.EOS data of various WDM systems obtained with PIMC simulations are then summarized,with which the advantages and disadvantages of PIMC method are illustrated.Finally,some future prospects of PIMC method are discussed.
