Identifying an effective model for the two-stage-Kondo regime: Numerical renormalization group results
P. A. Almeida, E. Vernek, E. V. Anda +2
A composite impurity in a metal can explore different configurations, where its net magnetic moment may be screened by the host electrons. An example is the two-stage Kondo (TSK) s…
Quantum impurity with 2/3 local moment in 1D quantum wires: an NRG study
P. A. Almeida, M. A. Manya, M. S. Figueira +3
We study a Kondo state that is strongly influenced by its proximity to an w^-1/2 singularity in the metallic host density of states. This singularity occurs at the bottom of the ba…
Transport properties of strongly correlated electrons in quantum dots using a simple circuit model
G. B. Martins, C. A. Busser, K. A. Al-Hassanieh +3
Numerical calculations are shown to reproduce the main results of recent experiments involving nonlocal spin control in nanostructures (N. J. Craig et al., Science 304, 565 (2004))…
Time Dependent Current Oscillations Through a Quantum Dot
E. S. Rodrigues, E. V. Anda, P. Orellana
Time dependent phenomena associated to charge transport along a quantum dot in the charge quantization regime is studied. Superimposed to the Coulomb blockade behaviour the current…
