Towards an effective mass model for the quasi-1D magnesium diboride superconducting nanostructures
Wojciech Julian Pasek, Marcos H. Degani, Marcio C. de Andrade +1
We developed a parabolic effective mass model with the aim to describe the in-plane constricted superconductivity in few-monolayer MgB. The model was employed to study a constr…
Optimal control of universal quantum gates in a double quantum dot
Leonardo K. Castelano, Emanuel F. de Lima, Justino R. Madureira +2
We theoretically investigate electron spin operations driven by applied electric fields in a semiconductor double quantum dot (DQD). Our model describes a DQD formed in semiconduct…
Application of the Landau-Zener-Stueckelberg-Majorana dynamics in an electrically driven flip of a hole spin
Wojciech Julian Pasek, Marcelo Zoega Maialle, Marcos Henrique Degani
An idea of employing the Landau-Zener-Stückelberg-Majorana (LZSM) dynamics to flip a spin of a single ground state hole is introduced and explored by a time-dependent simulation. T…
Negative photoconductance in a biased multiquantum well with filter barriers
Anibal T. Bezerra, Marcelo Z. Maialle, Marcos H. Degani +2
In this paper the photon-assisted electron motion in a multiquantum well (MQW) semiconductor heterostructure in the presence of an electric field is investigated. The time-dependen…
Generation and control of spin-polarized photocurrents in GaMnAs heterostructures
Anibal T. Bezerra, Leonardo K. Castelano, Marcos H. Degani +3
Photocurrents are calculated for a specially designed GaMnAs semiconductor heterostructure. The results reveal regions in the infrared range of the energy spectrum in which the pro…
Terahertz-field induced tunneling current with non-linear effects in a double quantum well coupled to a continuum
Marcelo Z. Maialle, Marcos H. Degani, Justino R. Madureira +1
We have theoretically investigated the tunneling current induced by a terahertz (THz) field applied to an asymmetric double quantum well. The excitation couples an initially locali…
