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…
Two-state behaviour of Kondo trimers
M. E. Torio, K. Hallberg, C. R. Proetto
The electronic properties and spectroscopic features of a magnetic trimer with a Kondo-like coupling to a non-magnetic metallic substrate are analyzed at zero temperature. The subs…
Coulomb interaction effects on the electronic structure of radial polarized excitons in nanorings
Z. Barticevic, M. Pacheco, J. Simonin +1
The electronic structure of radially polarized excitons in structured nanorings is analyzed, with emphasis in the ground-state properties and their dependence under applied magneti…
Evidence of spontaneous spin polarization in the two-dimensional electron gas
A. R. Goñi, P. Giudici, F. A. Reboredo +4
Density-functional calculations using an exact exchange potential for a two-dimensional electron gas (2DEG) formed in a GaAs single quantum well predict the existence of a spin-pol…
Partially confined excitons in semiconductor nanocrystals with a finite size dielectric interface
Pablo G. Bolcatto, Cesar R. Proetto
The combined effect of finite potential barriers and dielectric mismatch between dot and matrix on excitonic properties of semiconductor quantum dots has been studied. To avoid the…
