Koopmans spectral functionals are a class of orbital-density-dependent functionals designed to accurately predict spectroscopic properties. They do so markedly better than their Kohn-Sham density-functional theory counterparts, as demonstrated in earlier works on benchmarks of molecules and bulk systems. This work is a complementary study where — instead of comparing against real, many-electron systems — we test Koopmans spectral functionals on Hooke's atom, a toy two-electron system that has an analytical solution. As these calculations clearly illustrate, Koopmans spectral functionals do an excellent job of describing Hooke's atom. This work also provides broader insight into the features and capabilities of Koopmans spectral functionals more generally. This repository contains data associated with the article of the same name.
