Enhancement of the thermoelectric efficiency in a T-shaped quantum dot system in the linear and nonlinear regimes
G. Gómez-Silva, P. A. Orellana, E. V. Anda
In the present work, we investigate the thermoelectric properties of a T-shaped double quantum dot system coupled to two metallic leads incorporating the intra-dot Coulomb interact…
The crossover and spin filter properties of a double quantum dot nanosystem
V. Lopes, R. A. Padilla, G. B. Martins +1
The crossover, driven by an external magnetic field , is analyzed in a capacitively-coupled double-quantum-dot device connected to independent leads. As one contin…
Selfconsistent hybridization expansions for static properties of the Anderson impurity model
I. J. Hamad, P. Roura-Bas, A. A. Aligia +1
By means of a projector-operator formalism we derive an approximation based on a self consistent hybridization expansion to study the ground state properties of the Anderson Impuri…
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.…
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…
Fano-Kondo and the Kondo-box regimes crossover in a quantum dot coupled to a quantum box
V. M. Apel, Pedro A. Orellana, Monica Pacheco +1
In this work,we study the Kondo effect of a quantum dot (QD) connected to leads and to a discrete set of one particle states provided by a quantum box represented by a quantum ring…
