Effects of varying curvature and width on the electronic states of GaAs quantum rings
(Sociedade Brasileira de Física, 2006-06-01)
Stationary states of an electron in thin GaAs elliptical quantum rings are calculated within the effective-mass approximation. The width of the ring varies smoothly along the centerline, which is an ellipse. The solutions ...

Electric currents induced by twisted light in quantum rings
(Optical Society of America, 2009-10)
We theoretically investigate the generation of electric currents in quantum rings resulting from the optical excitation with twisted light. Our model describes the kinetics of electrons in a two-band model of a semiconductor-based ...
Structural properties of nanoscopic ring systems and their optical response
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2016-03-30)
In this thesis, the electronic and structural properties of nanostructured systems were studied aiming to get a realistic model for quantum rings, potentially adaptable for quantum dots. To attain these goals, several ...

Control of the persistent currents in two interacting quantum rings through the Coulomb interaction and interring tunneling
(AMER PHYSICAL SOC, 2008)
The persistent current in two vertically coupled quantum rings containing few electrons is studied. We find that the Coulomb interaction between the rings in the absence of tunneling affects the persistent current in each ...
