Anticrossings in Foerster Coupled Quantum Dots
arXiv:quant-ph/0309099 · doi:10.1103/PhysRevB.71.045334
Abstract
We consider two coupled generic quantum dots, each modelled by a simple potential which allows the derivation of an analytical expression for the inter-dot Foerster coupling, in the dipole-dipole approximation. We investigate the energy level behaviour of this coupled two-dot system under the influence of an external applied electric field and predict the presence of anticrossings in the optical spectra due to the Foerster interaction.
