Orbital-optimized density functional calculations of excited electronic states: Recent advances and perspectives
Lorenzo Restaino, Giulia Gamboni, Elli Selenius +1
Orbital-optimized (OO) density functional calculations provide a time-independent, variational route to electronic excitations, alternative to presently widely used time-dependent…

A unified formalism for collinear and non-collinear approaches in the four-component Dirac-Kohn-Sham theory based on G-spinors
Giulia Gamboni, Loriano Storchi, Paola Belanzoni +1
Non-collinear density functional theories were developed to extend the use of established collinear exchange-correlation functionals to systems with unpaired electrons in the prese…
