Coupling effects on Rabi oscillations in quantum dots chains
چکیده انگلیسی
In this work, we calculate the temporal evolution of electronic states under AC electric fields. We do that by obtaining the eigenenergies and wave functions of states of the first two minibands for arrays of 10 cylindrical quantum dots, both vertically and laterally coupled, which exhibit notable difference in their symmetry levels and coupling magnitudes. We observe an important dependence of the Rabi amplitude on the wave function symmetry and the coupling magnitude, and conclude that Rabi oscillations at the terahertz range are best suited for the higher coupling between dots.
