Cox, Joel ; Singh, Mahi R. ; Gumbs, Godfrey ; Antón Revilla, Miguel Ángel ; Carreño Sánchez, Fernando | American Physical Society | 2012-09-28We study theoretically the dipole-dipole interaction and energy transfer in a hybrid system consisting of a quantum dot and graphene nanodisk embedded in a nonlinear photonic crystal. In our model, a probe laser field is applied to measure the e[...]texto impreso
Antón Revilla, Miguel Ángel ; Carreño Sánchez, Fernando ; Melle Hernández, Sonia ; Gómez Calderón, Óscar ; Cabrera Granado, Eduardo ; Singh, Mahi R. | American Physical Society | 2013-05-07The preparation of quantum states with a defined spin is analyzed in a hybrid system consisting of a p-doped semiconductor quantum dot (QD) coupled to a metallic nanoparticle. The quantum dot is described as a four-level atom-like system using [...]texto impreso
Carreño Sánchez, Fernando ; Antón Revilla, Miguel Ángel ; Melle Hernández, Sonia ; Gómez Calderón, Óscar ; Cabrera Granado, Eduardo ; Cox, Joel ; Singh, Mahi R. ; Egatz-Gómez, Ana | American Institute of Physics Publising | 2014A scheme for terahertz (THz) generation from intraband transition in a self-assembled quantum dot (QD) molecule coupled to a metallic nanoparticle (MNP) is analyzed. The QD structure is described as a three-level atom-like system using the densi[...]texto impreso
Cox, Joel D. ; Singh, Mahi R. ; Antón Revilla, Miguel Ángel ; Carreño Sánchez, Fernando | IOP Publishing Ltd. | 2013-08-29Nonlinear two-photon absorption in a quantum dot–graphene nanoflake nanocomposite system has been investigated. An external laser field is applied to the nanocomposite to simultaneously observe two-photon processes in the quantum dot and excite [...]texto impreso
Antón Revilla, Miguel Ángel ; Carreño Sánchez, Fernando ; Melle Hernández, Sonia ; Calderón, Oscar Gómez ; Cabrera Granado, Eduardo ; Cox, Joel ; Singh, Mahi R. | American Physical Society | 2012We have investigated the coherent transfer of excitonic populations in a semiconductor quantum dot (SQD) modulated by the surface plasmon of a metallic nanoparticle (MNP). The SQD is considered as a three-level V-type atomic system. We applied a[...]
