库仑算子的分辨率:VI。辅助积分的计算

Resolutions of the Coulomb operator: VI. Computation of auxiliary integrals

Taweetham Limpanuparb, Joshua W. Hollett, Peter M. W. Gill

摘要:

我们讨论了有效的计算时产生的辅助积分的决议时,两个电子运营商(特别是库仑和远程埃瓦尔德运营商)采用量子化学计算。我们推导出一个递推关系,便于生成任意角动量的高斯基函数的辅助积分,并提出了一个接近最佳的算法。

英文摘要:

We discuss the efficient computation of the auxiliary integrals that arise when resolutions of two-electron operators (specifically, the Coulomb and long-range Ewald operators) are employed in quantum chemical calculations. We derive a recurrence relation that facilitates the generation of auxiliary integrals for Gaussian basis functions of arbitrary angular momentum and propose a near-optimal algorithm for its use.
