Abstract

The magneto-optical response to far-infrared radiation of quantum dots containing two electrons is studied theoretically. The symmetry-breaking effects of deviations from a strictly parabolic confinement potential are emphasized. We demonstrate the evidence of many-particle effects in systems where the generalized Kohn's theorem is no longer applicable. The calculated resonance spectrum reflects and explains all features observed in recent high-resolution measurements.
