Magnetic field modulated Kondo effect in a single-magnetic-ion molecule
Javier I. Romero, E. Vernek, G. B. Martins +1
We study numerically the low-temperature electronic transport properties of a single-ion magnet with uniaxial and transverse spin anisotropies. We find clear signatures of a Kondo…
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…
Capacitively coupled double quantum dot system in the Kondo regime
Irisnei L. Ferreira, P. A. Orellana, G. B. Martins +2
A detailed study of the low-temperature physics of an interacting double quantum dot system in a T-shape configuration is presented. Each quantum dot is modeled by a single Anderso…
Transport in Carbon Nanotubes: 2LSU(2) regime reveals subtle competition between Kondo and Intermediate Valence states
C. A. Busser, E. Vernek, P. Orellana +5
In this work, we use three different numerical techniques to study the charge transport properties of a system in the two-level SU(2) (2LSU2) regime, obtained from an SU(4) model H…
Transport and Strong-Correlation Phenomena in Carbon Nanotube Quantum Dots in a Magnetic Field
M. Mizuno, Eugene H. Kim, G. B. Martins
Transport through carbon nanotube (CNT) quantum dots (QDs) in a magnetic field is discussed. The evolution of the system from the ultraviolet to the infrared is analyzed; the stron…
Kondo regime in triangular arrangements of quantum dots: Molecular orbitals, interference and contact effects
E. Vernek, C. A. Busser, G. B. Martins +3
Transport properties of an interacting triple quantum dot system coupled to three leads in a triangular geometry has been studied in the Kondo regime. Applying mean-field finite-U…
