The article, "Implementation of Perdew–Zunger self-interaction correction in real space using Fermi–Löwdin orbitals," is published on Journal of Chemical Physics on 2021-2-23 [J. Chem. Phys. 154, 084112 (2021); doi: 10.1063/5.0031341]. In this work, we discuss implementation of FLOSIC on to SPARC real-space electronic structure code and show some benchmark calculations. This real-space formulation provides an accurate and systematically improvable approach for FLOSIC calculations in the Slater-average form.
