We introduce a mixed density fitting scheme that uses both a Gaussian and a plane-wave fitting basis to accurately evaluate electron repulsion integrals in crystalline systems. We use this scheme to enable efficient all-electron Gaussian based periodic density functional and Hartree-Fock calculations.
我们引入了一种混合密度拟合方案，该方案同时使用高斯和平面波拟合基来精确评估晶体系统中的电子排斥积分。我们使用该方案实现了高效的全电子基于高斯的周期性密度泛函和 Hartree-Fock 计算。
