Missing derivative discontinuity of the exchange-correlation energy for attractive interactions: the charge Kondo effect
E. Perfetto, G. Stefanucci
We show that the energy functional of ensemble Density Functional Theory (DFT) [Perdew et al., Phys. Rev. Lett. 49, 1691 (1982)] in systems with attractive interactions is a convex…

Renormalization of the Coulomb blockade gap due to extended tunneling in nanoscopic junctions
E. Perfetto
In this work we discuss the combined effects of finite-range electron-electron interaction and finite-range tunneling on the transport properties of ultrasmall tunnel junctions. We…
