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…
Exact-exchange Kohn-Sham potential, surface energy, and work function of jellium slabs
C. M. Horowitz, C. R. Proetto, J. M. Pitarke
Exact-exchange self-consistent calculations of the Kohn-Sham potential, surface energy, and work function of jellium slabs are reported in the framework of the Optimized Effective…
Electronic exchange in quantum rings
E. Rasanen, S. Pittalis, C. R. Proetto +1
Quantum rings can be characterized by a specific radius and ring width. For this rich class of physical systems, an accurate approximation for the exchange-hole potential and thus…
Signatures of Discontinuity in the Exchange-Correlation Energy Functional Derived from the Subband Electronic Structure of Semiconductor Quantum Wells
S. Rigamonti, C. R. Proetto
The discontinuous character of the exact exchange-correlation energy functional of Density Functional Theory is shown to arise naturally in the subband spectra of semiconduc…
