【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.更多还原
