Spin-Forster transfer in optically excited quantum dots
arXiv:cond-mat/0503688 · doi:10.1103/PhysRevB.71.155323
Abstract
The mechanisms of energy and spin transfer in quantum dot pairs coupled via the Coulomb interaction are studied. Exciton transfer can be resonant or phonon-assisted. In both cases, the transfer rates strongly depend on the resonance conditions. The spin selection rules in the transfer process come from the exchange and spin-orbit interactions. The character of energy dissipation in spin transfer is different than that in the traditional spin currents. The spin-dependent photon cross-correlation functions reflect the exciton transfer process. In addition, a mathematical method to calculate Förster transfer in crystalline nanostructures beyond the dipole-dipole approximation is described.
