Efficient single-grid and multi-grid solvers for real-space orbital-free density functional theory
Ling-Ze Bu, Wei Wang
To improve the computational efficiencies of the real-space orbital-free density functional theory, this work develops a new single-grid solver by directly providing the closed-for…

Tensor train-Karhunen-Loève expansion for continuous-indexed random fields using higher-order cumulant functions
Ling-Ze Bu, Wei Zhao, Wei Wang
The goals of this work are two-fold: firstly, to propose a new theoretical framework for representing random fields on a large class of multidimensional geometrical domain in the t…
