Efficient real space formalism for hybrid density functionals
Xin Jing, Phanish Suryanarayana
We present an efficient real space formalism for hybrid exchange-correlation functionals in generalized Kohn-Sham density functional theory (DFT). In particular, we develop an effi…
On-the-fly machine learned force fields for the study of warm dense matter: application to diffusion and viscosity of CH
Shashikant Kumar, Xin Jing, John E. Pask +1
We develop a framework for on-the-fly machine learned force field (MLFF) molecular dynamics (MD) simulations of warm dense matter (WDM). In particular, we employ an MLFF scheme bas…
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…

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…
Version 2.0.0 -- M-SPARC: Matlab-Simulation Package for Ab-initio Real-space Calculations
Boqin Zhang, Xin Jing, Shashikant Kumar +1
M-SPARC is a Matlab code for performing ab initio Kohn-Sham Density Functional Theory simulations. Version 2.0.0 of the software further extends its capability to include relativis…
Real-space density kernel method for Kohn-Sham density functional theory calculations at high temperature
Qimen Xu, Xin Jing, Boqin Zhang +2
Kohn-Sham density functional theory calculations using conventional diagonalization based methods become increasingly expensive as temperature increases due to the need to compute…
