Effects of nonorthogonality in the time-dependent current through tunnel junctions
J. Fransson, O. Eriksson, I. Sandlov
A theoretical technique which allows to include contributions from non-orthogonality of the electron states in the leads connected to a tunneling junction is derived. The theory is…
On the non-orthogonality problem in the description of quantum devices
J. Fransson, O. Eriksson, B. Johansson +1
An approach which allows to include the corrections from non-orthogonality of electron states in contacts and quantum dots is developed. Comparison of the energy levels and charge…
Correlation mechanism of the f-electron delocalization
U. Lundin, I. Sandalov, O. Eriksson +1
The mechanism of f-electron delocalization is investigated within the multi-orbital Anderson lattice model by means of diagrammatic perturbation theory from the atomic limit. The d…
Modification of the standard model for the lanthanides
U. Lundin, I. Sandalov, O. Eriksson +1
We show that incorporation of strong electron correlations into the Kohn-Sham scheme of band structure calculations leads to a modification of the standard model of the lanthanides…
