Gonzalez-Santander, C ; Orellana, P. A. ; Domínguez-Adame Acosta, Francisco | EPL Association, European Physical Society | 2013-04We report on the formation of bound states in the continuum driven by AC fields. The considered system consists of a quantum ring connected to two leads. An AC side-gate voltage controls the interference of electrons passing through the system. [...]texto impreso
A system of an array of side-coupled quantum dots attached to a quantum wire is studied theoretically. Transport through the quantum wire is investigated by means of a noninteracting Anderson tunneling Hamiltonian. Analytical expressions of the [...]texto impreso
Saiz-Bret´?n, M. ; Malyshev, Andrey ; Orellana, P. A. ; Domínguez-Adame Acosta, Francisco | American Physical Society | 2015-02-27We study the thermoelectric properties of rectangular graphene rings connected symmetrically or asymmetrically to the leads. A side-gate voltage applied across the ring allows for the precise control of the electric current flowing through the s[...]texto impreso
We consider the electronic transport through a Rashba quantum dot coupled to ferromagnetic leads. We show that the interference of localized electron states with resonant electron states leads to the appearance of the Fano-Rashba effect. This ef[...]texto impreso
Munarriz, J. ; Domínguez-Adame Acosta, Francisco ; Orellana, P. A. ; Malyshev, Andrey | IOP publishing ltd | 2012-05-25We propose a novel spin filter based on a graphene nanoring fabricated above a ferromagnetic strip. The exchange interaction between the magnetic moments of the ions in the ferromagnet and the electron spin splits the electronic states, and give[...]texto impreso
Álvarez, C ; Domínguez-Adame Acosta, Francisco ; Orellana, P. A. ; Díaz García, Elena | Elsevier | 2015-06-12We investigate the nonequilibrium transport properties of a coupled quantum dot system connected in parallel to two leads, including electron-vibron interaction. It is known that in the absence of interaction the system supports a bound state in[...]texto impreso
Malyshev, Andrey ; Orellana, P. A. ; Domínguez-Adame Acosta, Francisco | American Physical Society | 2006-07Electronic transport properties of two quantum dots side-coupled to a quantum wire are studied by means of the two impurity Anderson Hamiltonian. The conductance is found to be a superposition of Fano and Breit-Wigner resonances as a function of[...]texto impreso
Núñez, C. ; Orellana, P. A. ; Rosales, L. ; Römer, R. A. ; Domínguez-Adame Acosta, Francisco | American Physical Society | 2017-07-06We investigate the nonequilibrium transport properties of a silicene armchair nanoribbon with a random distribution of adsorbed atoms in apex positions. A ferromagnetic insulator grown below the nanoribbon splits spin-up and spin-down electron b[...]texto impreso
Munarriz, J. ; Gaul, C. ; Malyshev, Andrey ; Orellana, P. A. ; Mueller, C. A. ; Domínguez-Adame Acosta, Francisco | American Physical Society | 2013-10We find clear signatures of spin-dependent negative differential resistance in compound systems comprising a graphene nanoribbon and a set of ferromagnetic insulator strips deposited on top of it. The periodic array of ferromagnetic strips induc[...]texto impreso
Gómez, I. ; Díez, E. ; Domínguez-Adame Acosta, Francisco ; Orellana, P. A. | American Institute of Physics | 2002-10-15We present a model based on the two-dimensional transfer matrix formalism to calculate single-electron states in a random wide-gap semiconductor quantum dot superlattice. With a simple disorder model both the random arrangement of quantum dots ([...]texto impreso
Orellana, P. A. ; Domínguez-Adame Acosta, Francisco ; Gómez, I. ; Guevara, M.L..L, de | American Physical Society | 2003-02-15A noninteracting quantum-dot array side coupled to a quantum wire is studied. Transport through the quantum wire is investigated by using a noninteracting Anderson tunneling Hamiltonian. The conductance at zero temperature develops an oscillatin[...]texto impreso
Ahumada, M. ; Orellana, P. A. ; Domínguez-Adame Acosta, Francisco ; Malyshev, Andrey | American Physical Society | 2019-03-14We propose an efficient single-photon router comprising two resonator waveguide channels coupled by several sequential cavities with embedded three-level atoms. We show that the system can operate as a perfect four-way single-photon switch. We a[...]texto impreso
Núñez, C. ; Saiz Bretín, M. ; Orellana, P. A. ; Rosales, L. ; Domínguez-Adame Acosta, Francisco | IOP Publishing | 2020-06-24In this work, we present a thorough study of the thermoelectric properties of silicene nanoribbons in the presence of a random distribution of atomic vacancies. By using a linear approach within the Landauer formalism, we calculate phonon and el[...]
