Comparison of three different self-interaction corrections for an exactly solvable model system
Daniel Vieira, K. Capelle
A systematic comparison of three approximate self-interaction corrections (SICs), Perdew-Zunger SIC, Lundin-Eriksson SIC and extended Fermi-Amaldi SIC, is performed for a model Ham…

Density-functional description of superconducting and magnetic proximity effects across a tunneling barrier
Jorge Quintanilla, Klaus Capelle, Luiz N. Oliveira
A density-functional formalism for superconductivity {\em and} magnetism is presented. The resulting relations unify previously derived Kohn-Sham equations for superconductors and…

Universal and nonuniversal contributions to block-block entanglement in many-fermion systems
Vivian V. Franca, Klaus Capelle
We calculate the entanglement entropy of blocks of size x embedded in a larger system of size L, by means of a combination of analytical and numerical techniques. The complete enta…
