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…
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…
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…
Charge and spin conductance through a side-coupled quantum dot
M. E. Torio, K. Hallberg, C. Proetto
The zero-temperature magnetic field-dependent conductance of electrons through a one-dimensional non-interacting tight-binding chain with an interacting {\it side} dot is reviewed…
