A novel splitting strategy to accelerate solving generalized eigenvalue problem from Kohn--Sham density functional theory
Yang Kuang, Guanghui Hu
In this paper, we propose a novel eigenpair-splitting method, inspired by the divide-and-conquer strategy, for solving the generalized eigenvalue problem arising from the Kohn-Sham…
