Tunable mode entanglement: topological Su-Schrieffer-Heeger (SSH) chain with an embedded Aharonov-Bohm quantum ring
A. P. Garrido, A. R. Plastino, M. L. Ladrón de Guevara +1
We investigate a variant of the SSH model consisting of an SSH chain with an embedded Aharonov-Bohm quantum ring. The embedded ring gives rise to domain wall states whose energy le…
Fano-Andreev effect in T-shape double-quantum-dot in the Kondo regime
A. M. Calle, M. Pacheco, G. B. Martins +3
In the present work, we investigate the electronic transport through a T-shape double quantum dot system coupled to two normal leads and to one superconducting lead. We explore the…
Single-parameter spin-pumping in driven metallic rings with spin-orbit coupling
J. P. Ramos, L. E. F. Foa Torres, P. A. Orellana +1
We consider the generation of a pure spin-current at zero bias voltage with a single time-dependent potential. To such end we study a device made of a mesoscopic ring connected to…
Fano-Kondo and the Kondo-box regimes crossover in a quantum dot coupled to a quantum box
V. M. Apel, Pedro A. Orellana, Monica Pacheco +1
In this work,we study the Kondo effect of a quantum dot (QD) connected to leads and to a discrete set of one particle states provided by a quantum box represented by a quantum ring…
Fano and Dicke effects and spin polarization in a double Rashba-ring system side coupled to a quantum wire
V. M. Apel, P. A. Orellana, M. Pacheco
The electronic transport in a system of two quantum rings side-coupled to a quantum wire is studied via a single-band tunneling tight-binding Hamiltonian. We derived analytical exp…
Phase Effects on the Conductance Through Parallel Double Dots
V. M. Apel, Maria A. Davidovich, G. Chiappe +1
Phase effects on the conductance of a double-dot system in a ring structure threaded by a magnetic flux are studied. The Aharonov-Bohm effect combined with the dot many-body chargi…
