Anisotropic Kondo screening induced by spin-orbit coupling in quantum wires
E. Vernek, G. B. Martins, R. Zitko
Using the numerical renormalization group (NRG) method we study a magnetic impurity coupled to a quantum wire with Rashba and Dresselhaus spin-orbit coupling (SOC) in an external m…
Reentrant Kondo effect in a quantum impurity coupled to a metal-semiconductor hybrid contact
G. Diniz, G. S. Diniz, G. B. Martins +1
Using NRG, we show that a system containing a quantum impurity (QI), strongly coupled to a semiconductor (gap ) and weakly coupled to a metal, displays a 'reentrant' Kondo sta…
From Kondo to local singlet state in graphene nanoribbons with magnetic impurities
G. S. Diniz, G. I. Luiz, A. Latgé +1
A detailed analysis of the Kondo effect of a magnetic impurity in a zigzag graphene nanoribbon is addressed. An adatom is coupled to the graphene nanoribbon via a hybridization amp…
Interaction effects on a Majorana zero mode leaking into a quantum dot
David A. Ruiz-Tijerina, E. Vernek, Luis G. G. V. Dias da Silva +1
We have recently shown [Phys. Rev. B {\bf 89}, 165314 (2014)] that a non--interacting quantum dot coupled to a one--dimensional topological superconductor and to normal leads can s…
Capacitive interactions and Kondo effect tuning in double quantum impurity systems
David A. Ruiz-Tijerina, E. Vernek, Sergio E. Ulloa
We present a study of the correlated transport regimes of a double quantum impurity system with mutual capacitive interactions. Such system can be implemented by a double quantum d…
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…
