Kohn-Sham accuracy from orbital-free density functional theory via -machine learning
Shashikant Kumar, Xin Jing, John E. Pask +2
We present a -machine learning model for obtaining Kohn-Sham accuracy from orbital-free density functional theory (DFT) calculations. In particular, we employ a machine learned…
Accuracy of Kohn-Sham density functional theory for warm- and hot-dense matter equation of state
Phanish Suryanarayana, Arpit Bhardwaj, Xin Jing +2
We study the accuracy of Kohn-Sham density functional theory (DFT) for warm- and hot-dense matter (WDM and HDM). Specifically, considering a wide range of systems, we perform accur…
Version 2.0.0 -- SPARC: Simulation Package for Ab-initio Real-space Calculations
Boqin Zhang, Xin Jing, Qimen Xu +8
SPARC is an accurate, efficient, and scalable real-space electronic structure code for performing ab initio Kohn-Sham density functional theory calculations. Version 2.0.0 of the s…
Assessing the source of error in the Thomas-Fermi-von Weizsäcker density functional
Bishal Thapa, Xin Jing, John E. Pask +2
We investigate the source of error in the Thomas-Fermi-von Weizsäcker (TFW) density functional relative to Kohn-Sham density functional theory (DFT). In particular, through numeric…
