Kondo screening regimes of a quantum dot with a single Mn ion
E. vernek, Fanyao Qu, F. M. Souza +2
We study the Kondo and transport properties of a quantum dot with a single magnetic Mn ion connected to metallic leads. By employing a numerical renormalization group technique we…
Transport in Carbon Nanotubes: 2LSU(2) regime reveals subtle competition between Kondo and Intermediate Valence states
C. A. Busser, E. Vernek, P. Orellana +5
In this work, we use three different numerical techniques to study the charge transport properties of a system in the two-level SU(2) (2LSU2) regime, obtained from an SU(4) model H…
Kondo regime in triangular arrangements of quantum dots: Molecular orbitals, interference and contact effects
E. Vernek, C. A. Busser, G. B. Martins +3
Transport properties of an interacting triple quantum dot system coupled to three leads in a triangular geometry has been studied in the Kondo regime. Applying mean-field finite-U…
Phonon-assisted tunneling regimes in diatomic molecules
E. Vernek, E. V. Anda, S. E. Ulloa +1
Electronic transport in diatomic molecules (two-level systems) connected to metallic contacts is analyzed in the presence of competing electron-electron and electron-phonon interac…
Finite band effects over the linear conductance through a quantum wire coupled with a quantum dot: X-boson treatment
R. Franco, E. V Anda, M. S. Figueira
We study the electronic transport through a quantum wire (QW) with a strong side coupled quantum dot (QD). We obtain a linear conductance with lateral peaks when the gate voltage,…
