Exchange coupling for excitons in quantum wires |
|
| Authors: | D Larousserie R Ferreira |
| Abstract: | We consider theoretically the exchange coupling for independent heavy excitons in both weakly and strongly confining quantum wires. We discuss different contributions for the spin depolarization in the presence of spin-conserving scatterings and show that localization effects weaken the spin depolarization rate. |
