Transport Regimes in a Double Quantum Dot Device
L. Costa Ribeiro, I. J. Hamad, G. Chiappe +1
We analyze the transport properties of a double quantum dot device with both dots coupled to perfect conducting leads and to a finite chain of N non-interacting sites connecting bo…
Transport properties of a two impurity system: a theoretical approach
I. J. Hamad, L. Costa Ribeiro, G. B. Martins +1
A system of two interacting cobalt atoms, at varying distances, was studied in a recent scanning tunneling microscope experiment by Bork et. al.[Nature Phys. 7, 901 (2011)]. We pro…
Kondo temperature and screening extension in a double dot system
L. C. Ribeiro, E. Vernek, G. B. Martins +1
In this work we use the Slave Boson Mean Field Approximation at finite U to study the effects of spin-spin correlations in the transport properties of two quantum dots coupled in s…
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…
