Impurezas quanticas em sistemas com interação spin-órbita
(Universidade Federal de UberlândiaBrasilPrograma de Pós-graduação em Física, 2017)
Finite-temperature properties of the two-orbital Anderson model
(Iop Publishing LtdBristolInglaterra, 1999)
Electron Tunneling Excitation of a Coupled Two Impurity System
(Springer, 2018)
Kondo effects in individual atoms, molecular magnets or quantum dotshave received a lot of attention. Systems with two units, like double quantum dotsor two atoms, have also attracted some attention due to the interplay ...
Nonequilibrium transport through magnetic vibrating molecules
(American Physical Society, 2013-05)
We calculate the nonequilibrium conductance through a molecule or a quantum dot in which the occupation of the relevant electronic level is coupled with intensity λ to a phonon mode and also to two conducting leads. The ...
Electronic transport through a quantum wire with a side-coupled quantum dot
(Sociedade Brasileira de Física, 2006)
Quasiparticle Mass Enhancement as a Measure of Entanglement in the Kondo Problem
(American Physical Society, 2020-11)
We analyze the quantum entanglement between opposite spin projection electrons in the ground state of the Anderson impurity model. In this model, a single level impurity with intralevel repulsion U is tunnel coupled to a ...
SU(4) Kondo entanglement in double quantum dot devices
(American Physical Society, 2017-08-28)
We analyze, from a quantum information theory perspective, the possibility of realizing an SU(4) entangled Kondo regime in semiconductor double quantum dot devices. We focus our analysis on the ground-state properties and ...
Quantum Phase Transition Between One-channel and Two-channel Kondo Polarons
(American Physical Society, 2013-10)
For a mobile spin-1/2 impurity, coupled antiferromagnetically to a one-dimensional gas of fermions, perturbative ideas have been used to argue in favor of two-channel Kondo behavior of the impurity spin. Here we combine ...
