Fano-Andreev effect in a T-shaped Double Quantum Dot in the Coulomb blockade regime
A. González I., A. M. Calle, M. Pacheco +2
We studied the effects of superconducting quantum correlations in a system consisting of two quantum dots, two normal leads, and a superconductor. Using the non-equilibrium Green's…
Interference effects induced by Andreev bound states in a hybrid nanostructure composed by a quantum dot coupled to ferromagnetic and superconductor leads
E. C. Siqueira, P. A. Orellana, A. C. Seridonio +3
In this work, it is considered a nanostructure composed by a quantum dot coupled to two ferromagnets and a superconductor. The transport properties of this system are studied withi…
Fano interference and a slight fluctuation of the Majorana hallmark
A. C. Seridonio, E. C. Siqueira, F. A. Dessotti +2
According to the Phys. Rev. B 84, 201308(R) (2011), an isolated Majorana state bound to one edge of a long enough Kitaev chain in the topological phase and connected to a quantum d…
Spin-dependent beating patterns in thermoelectric properties: Filtering the carriers of the heat flux in a Kondo adatom system
A. C. Seridonio, E. C. Siqueira, R. Franco +3
We theoretically investigate the thermoelectric properties of a spin-polarized two-dimensional electron gas hosting a Kondo adatom hybridized with an STM tip. Such a setup is treat…
The graphene sheet versus the 2DEG: a relativistic Fano spin-filter via STM and AFM tips
A. C. Seridonio, E. C. Siqueira, F. M. Souza +3
We explore theoretically the density of states (LDOS) probed by an STM tip of 2D systems hosting an adatom and a subsurface impurity,both capacitively coupled to AFM tips and trave…
Dimensionality effects in the LDOS of ferromagnetic hosts probed via STM: spin-polarized quantum beats and spin filtering
A. C. Seridonio, S. C. Leandro, L. H. Guessi +5
We theoretically investigate the local density of states (LDOS) probed by a STM tip of ferromagnetic metals hosting a single adatom and a subsurface impurity. We model the system v…
Magnetoresistance and transistor-like behavior of double quantum dots connected to ferromagnetic and superconductor leads
E. C. Siqueira, G. G. Cabrera
The electric current and the magnetoresistance effect are studied in a double quantum-dot system, where one of the dots QDa is coupled to two ferromagnetic electrodes (F1,F2), whil…
Andreev tunneling through a double quantum-dot system coupled to a ferromagnet and a superconductor: effects of mean field electronic correlations
E. C. Siqueira, G. G. Cabrera
We study the transport properties of a hybrid nanostructure composed of a ferromagnet, two quantum dots, and a superconductor connected in series. By using the non-equilibrium Gree…
