S. Q. Zhou, D. M. Ceperley

摘要:

提出了一种利用虚时间投影构造局域化单粒子波函数并由此确定晶格哈密顿参数的方法。我们将该方法应用到一个特定的无序势产生的光晶格实验和计算每个实例的障碍,等效晶格模型参数。然后确定Hubbard参数的概率分布。本地化和本征能量收敛的测试进行检查。

英文摘要:

We propose a method to construct localized single particle wave functions using imaginary time projection and thereby determine lattice Hamiltonian parameters. We apply the method to a specific disordered potential generated by an optical lattice experiment and calculate for each instance of disorder, the equivalent lattice model parameters. The probability distributions of the Hubbard parameters are then determined. Tests of localization and eigen-energy convergence are examined.
