Excited-state Properties Beyond the Excitation Energy from Orbital-Optimized Density Functional Calculations II: Absorption Spectra
Lorenzo Restaino, Diego Llorena Prieto, Jukka John +3
Absorption spectra up to 10 eV are calculated for a set of small molecules using a variational density functional approach in which the orbitals are optimized for each excited stat…

Excited-state Properties Beyond the Excitation Energy from Orbital-Optimized Density Functional Calculations I: Dipole Moments of Rydberg States
Lorenzo Restaino, Jukka John, Diego Llorena Prieto +3
Rydberg excited states are challenging to describe due to their highly diffuse character. Orbital-optimized density functional calculations typically provide more accurate values o…

Locally Scaled Self-Interaction Corrected Energy Functionals with Complex Optimal Orbitals
Jukka John, Hlynur Guðmundsson, Iðunn Björg Arnaldsdóttir +2
We present a fully variational locally scaled self-interaction corrected (SIC) energy functional using complex optimal orbitals. This represents an important milestone for fully va…
