We report smooth relativistic Hartree-Fock pseudopotentials (also known as averaged relativistic effective potentials) and spin-orbit operators for the atoms H to Ba and Lu to Hg. We remove the unphysical extremely nonlocal behavior resulting from the exchange interaction in a controlled manner, and represent the resulting pseudopotentials in an analytic form suitable for use within standard quantum chemistry codes. These pseudopotentials are suitable for use within Hartree-Fock and correlated wave function methods, including diffusion quantum Monte Carlo calculations.
我们报告了从氢(H)到钡(Ba)以及从镥(Lu)到汞(Hg)等原子的光滑相对论性哈特里 - 福克赝势(也称为平均相对论有效势)和自旋 - 轨道算符。我们以可控方式消除了由交换相互作用导致的非物理的极端非局域行为,并将所得赝势表示为适合在标准量子化学代码中使用的解析形式。这些赝势适用于哈特里 - 福克方法以及相关波函数方法,包括扩散量子蒙特卡罗计算。
