Implementation of Auxiliary Field Quantum Monte-Carlo Calculation with Python and Its Applications
摘要/Abstract
摘要：
辅助场量子蒙特卡罗方法是强关联电子体系常用的数值计算方法.使用Python语言，实现了单带Hubbard模型的辅助场量子蒙特卡罗数值计算的图形用户界面程序，并利用该程序计算了二维四方格子的基态能量.所实现的程序可以作为下一步开发的基础，解决其他强关联问题.
Abstract：
Auxiliary field quantum Monte-Carlo method is widely used for numerical calculation of strongly correlated electronic systems. A graphical user interface(GUI)for auxiliary field quantum Monte-Carlo calculation based-on single band Hubbard model has been implemented with Python programming language. The ground state energy of two-dimensional square lattices was calculated by the program,which can be used as a template for further development to solve other strong correlation problems.
