Exchange-Correlation Potentials and Energy Densities through Orbital Averaging and Aufbau Integration
Vaibhav Khanna, Bikash Kanungo, Jeffrey Hatch +2
Exchange-correlation potentials vxc and energy densities exc are derived for integer and fractional electron counts using an orbital-averaged Kohn-Sham inversion procedure. The ref…
