Lattice distortions and/or intercalation as ways to induce magnetism in a-FeSi2: a theoretical study
V. Zhandun, N. Zamkova, P. Korzhavyi +1
The possibilities to induce magnetism in the non-magnetic bulk alpha-FeSi2 by means of lattice distortions or intercalation with metal or non-metal ions of light elements is invest…
Effect of local environment on moment formation in iron silicides
N. G. Zamkova, V. S. Zhandun, S. G. Ovchinnikov +1
The effect of local environment on the formation of magnetic moments on Fe atoms in iron silicides are studied by combination of ab initio and model calculations. The suggested mod…
Quasiparticles in Iron Silicides: GW versus LDA
Natalie Zamkova, Vyacheslav Zhandun, Sergey Ovchinnikov +1
The angle-resolved photoemission spectroscopy, ARPES, is able to measure both the spectra and spectral weights of the quasiparticles in solids. Although it is common to interpret t…
Non-linear magneto-transport through small quantum dots at strong intra-dot correlations
I. Sandalov, R. G. Nazmitdinov
Nonlinear transport through a quantum dot is studied in the limit of weak and strong intra-dot Coulomb interaction. For the latter regime the nonequilibrium self-consistent mean fi…
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…
