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…
Decoherence of an entangled state of a strongly-correlated double quantum dot structure through tunneling processes
C. A. Büsser, I. de Vega, F. Heidrich-Meisner
We consider two quantum dots described by the Anderson-impurity model with one electron per dot. The goal of our work is to study the decay of a maximally entangled state between t…
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…
Designing a symmetry protected molecular device
Carlos A. Busser, Adrian E. Feiguin
Realizing a quantum transistor built of molecules or quantum dots has been one of the most ambitious challenges in nanotechnology. Even though remarkable progress has been made, be…
Full electrostatic control over polarized currents through spin-orbital Kondo effect
Carlos A. Busser, Adrian E. Feiguin, George B. Martins
Numerical calculations indicate that by suitably controlling the individual gate voltages of a capacitively coupled parallel double quantum dot, with each quantum dot coupled to on…
