TDDFT+$U$: Hubbard corrected approximate density-functional theory in the excited-state regime

Okan K. Orhan, David D. O'Regan

We develop a generalization of the Kohn-Sham density functional theory (KS-DFT) + Hubbard $U$ (DFT+$U$) method to the excited-state regime. This has the form of Hubbard $U$ correct…
