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…
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…
Subtle leakage of a Majorana mode into a quantum dot
E. Vernek, P. H. Penteado, A. C. Seridonio +1
We investigate quantum transport through a quantum dot connected to source and drain leads and side-coupled to a topological superconducting nanowire (Kitaev chain) sustaining Majo…
Parity oscillations of Kondo temperature in a single molecule break junction
B. M. F Resende, E. Vernek
We study the Kondo temperature () of a single molecule break junction. By employing a numerical renormalization group calculations we have found that depends dramaticall…
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…
Scanning Tunneling Microscope Operating as a Spin-diode
P. H. Penteado, F. M. Souza, A. C. Seridonio +2
We theoretically investigate spin-polarized transport in a system composed of a ferromagnetic Scanning Tunneling Microscope (STM) tip coupled to an adsorbed atom (adatom) on a host…
