- Abstract
Trabajo presentado en el 7th International Conference on Optics and Excitons in Confined Systems (OECS7), celebrado en Montpellier (Francia), del 3 al 7 de septiembre de 2001, In this paper we present calculations of the magneto-excitonic absorption spectrum for two different quantum ring geometries. Calculations are performed using a direct diagonalization of the single particle wavefunctions. Two different behaviours including the novel appearance of a ground state exciton with a finite angular momentum are described and calculations of the conditional correlation function are used to explore the nature of the exciton peaks.
