Lower Bounds on the Exchange-Correlation Energy in Reduced Dimensions
E. Rasanen, S. Pittalis, K. Capelle +1
Bounds on the exchange-correlation energy of many-electron systems are derived and tested. By using universal scaling properties of the electron-electron interaction, we obtain the…

Dependence of response functions and orbital functionals on occupation numbers
S. Kurth, C. R. Proetto, K. Capelle
Explicitly orbital-dependent approximations to the exchange-correlation energy functional of density functional theory typically not only depend on the single-particle Kohn-Sham or…

Correlation energy of two-dimensional systems: Toward non-empirical and universal modeling
S. Pittalis, E. Rasanen, C. Proetto +1
The capability of density-functional theory to deal with the ground-state of strongly correlated low-dimensional systems, such as semiconductor quantum dots, depends on the accurac…
