Optimized local basis set for Kohn-Sham density functional theory
Lin Lin, Jianfeng Lu, Lexing Ying +1
We develop a technique for generating a set of optimized local basis functions to solve models in the Kohn-Sham density functional theory for both insulating and metallic systems.…

Adaptive local basis set for Kohn-Sham density functional theory in a discontinuous Galerkin framework I: Total energy calculation
Lin Lin, Jianfeng Lu, Lexing Ying +1
Kohn-Sham density functional theory is one of the most widely used electronic structure theories. In the pseudopotential framework, uniform discretization of the Kohn-Sham Hamilton…
