Anisotropy and spin-fluctuation effects on the spectral properties of Shiba impurities
J. A. Andrade, Alejandro M. Lobos
We theoretically consider a quantum magnetic impurity coupled to a superconductor, and obtain the local density of states at the position of the impurity taking into account the ef…
SU(4) Kondo entanglement in double quantum dot devices
Rodrigo Bonazzola, J. A. Andrade, Jorge I. Facio +2
We analyze, from a quantum information theory perspective, the possibility of realizing a SU(4) entangled Kondo regime in semiconductor double quantum dot devices. We focus our ana…
Spin filtering and thermopower in star coupled quantum dot devices
J. A. Andrade, Pablo S. Cornaglia
We analyze the linear thermoelectric transport properties of devices with three quantum dots in a star configuration. A central quantum dot is tunnel-coupled to source and drain el…
Many-body dynamics of the decay of excitons of different charges in a quantum dot
J. A. Andrade, A. A. Aligia, Pablo S. Cornaglia
We calculate the photoluminescence spectrum of a single semiconductor quantum dot strongly coupled to a continuum as a function of light frequency, gate voltage, and magnetic field…
Kondo temperature when the Fermi level is near a step in the conduction density of states
J. Fernández, A. A. Aligia, P. Roura-Bas +1
The (111) surface of Cu, Ag and Au is characterized by a band of surface Shockley states, with constant density of states beginning slightly below the Fermi energy. These states as…
Scaling of conductance through quantum dots with magnetic field
I. J. Hamad, C. Gazza, J. A. Andrade +3
Using different techniques, and Fermi-liquid relationships, we calculate the variation with applied magnetic field (up to second order) of the zero-temperature equilibrium conducta…
Ferromagnetic and underscreened Kondo behavior in quantum dot arrays
J. A. Andrade, D. J. García, Pablo S. Cornaglia
We analyze the low energy properties of a device with quantum dots in a star configuration. A central quantum dot is tunnel coupled to source and drain electrodes and to …
Transport through side-coupled multilevel double quantum dots in the Kondo regime
J. A. Andrade, Pablo S. Cornaglia, A. A. Aligia
We analyze the transport properties of a double quantum dot device in the side-coupled configuration. A small quantum dot (QD), having a single relevant electronic level, is couple…
