Kondo versus indirect exchange: the role of the lattice and the actual range of RKKY interactions in real materials
Andrew Allerdt, C. A. Busser, G. B. Martins +1
Magnetic impurities embedded in a metal interact via an effective Ruderman-Kittel-Kasuya-Yosida (RKKY) coupling mediated by the conduction electrons, which is commonly assumed to b…
Polarized currents and spatial separation of Kondo state: NRG study of spin-orbital effect in a double QD
E. Vernek, C. A. Busser, E. V. Anda +2
A double quantum dot device, connected to two channels that only see each other through interdot Coulomb repulsion, is analyzed using the numerical renormalization group technique.…
Inducing spin-correlations and entanglement in a double quantum dot through non-equilibrium transport
C. A. Büsser, F. Heidrich-Meisner
For a double quantum dot system in a parallel geometry, we demonstrate that by combining the effects of a flux and driving an electrical current through the structure, the spin cor…
The spatial range of the Kondo effect: a numerical analysis
C. A. Büsser, G. B. Martins, L. Costa Ribeiro +3
The spatial length of the Kondo screening is still a controversial issue related to Kondo physics. While renormalization group and Bethe Anzats solutions have provided detailed inf…
A Novel Approach to Study Highly Correlated Nanostructures: The Logarithmic Discretization Embedded Cluster Approximation
E. V. Anda, G. Chiappe, C. A. Busser +4
This work proposes a new approach to study transport properties of highly correlated local structures. The method, dubbed the Logarithmic Discretization Embedded Cluster Approximat…
Transport through quantum dots: A combined DMRG and cluster-embedding study
F. Heidrich-Meisner, G. B. Martins, C. A. Busser +5
The numerical analysis of strongly interacting nanostructures requires powerful techniques. Recently developed methods, such as the time-dependent density matrix renormalization gr…
