KS-pies:Kohn-Sham反演工具包

KS-pies: Kohn-Sham Inversion Toolkit

Seungsoo Nam, Ryan J. McCarty, Hansol Park, Eunji Sim

摘要:

Kohn-Sham(KS)反演确定对应于给定电子密度的KS势和轨道,该过程在开发和评估密度泛函理论中使用的泛函中具有应用。尽管KS反演的实用性,这些方法的研究社区之间的应用是不成比例的小。我们实现了赵-莫里森-帕尔和吴-杨的KS反演方法的框架,简化了分析和转换所产生的潜在的实空间。完整文档的Python脚本与流行的电子结构预测软件PySCF集成,并为计算热点提供Fortran替代方案。

英文摘要:

A Kohn-Sham (KS) inversion determines a KS potential and orbitals corresponding to a given electron density, a procedure that has applications in developing and evaluating functionals used in density functional theory. Despite the utility of KS inversions, application of these methods among the research community is disproportionately small. We implement the KS inversion methods of Zhao-Morrison-Parr and Wu-Yang in a framework that simplifies analysis and conversion of the resulting potential in real-space. Fully documented Python scripts integrate with PySCF, a popular electronic structure prediction software, and Fortran alternatives are provided for computational hot spots.
