Nuclear magnetic relaxation for the spin-degenerate Anderson model
(Elsevier B.V., 2014)
Mesoscopic features in the transport properties of a Kondo-correlated quantum dot in a magnetic field
(IOP Publishing, 2013-12)
We study the transport behavior induced by a small bias voltage through a quantum dot connected to one-channel finite-size wires. We describe the quantum dot using the Hubbard–Anderson impurity model and we obtain solutions ...
From tunneling to contact in a magnetic atom: The non-equilibrium Kondo effect
(American Institute of Physics, 2017-03)
A low-temperature scanning tunneling microscope was employed to study the differential conductance in an atomic junction formed by an adsorbed Co atom on a Cu(100) surface and a copper-covered tip. A zero-bias anomaly (ZBA) ...
Comment on "Conductance scaling in Kondo-correlated quantum dots: Role of level asymmetry and charging energy"
(American Physical Society, 2014-08)
In a recent work [Merker, Kirchner, Muñoz, and Costi, Phys. Rev. B 87, 165132 (2013)], the authors compared the results of numerical renormalization group (NRG) and a perturbative approach for the dependence on temperature ...
Hybrid quantum dot - superconducting systems: Josephson current and Kondo effect in the narrow-band limit
(American Physical Society, 2015-01-30)
The case of a quantum dot connected to two superconducting leads is studied by using the narrow-band limit to describe the superconducting degrees of freedom. The model provides a simple theoretical framework, almost ...
Influence of Rashba spin-orbit coupling on the 0-π transition and Kondo temperature in one-dimensional superconductors
(American Physical Society, 2019-12)
Using the framework of the density-matrix renormalization group (DMRG), we study a quantum dot coupled to a superconducting nanowire with strong Rashba spin-orbit coupling. Regarding the singlet-to-doublet "0-π" transition ...
Fully compensated Kondo effect for a two-channel spin S=1 impurity
(American Physical Society, 2019-08-26)
We study the low-temperature properties of the generalized Anderson impurity model in which two localized configurations, one with two doublets and the other with a triplet, are mixed by two degenerate conduction channels. ...
Universal zero-bias conductance for the single-electron transistor
(AMER PHYSICAL SOC, 2009)
The thermal dependence of the zero-bias conductance for the single electron transistor is the target of two independent renormalization-group approaches, both based on the spin-degenerate Anderson impurity model. The first ...
