Abstract
The exact ion-electron and electron-electron interaction energies in quantum dots (QDs) with parabolic potentials are calculated and studied in detail. On the basis of calculated results, one- and two-electron spectra in QDs are revealed. It is found that the spectra are dramatically changed with the variation of the size and field. The even-parity-odd-parity and spin-singlet-spin-triplet oscillations with magnetic field are clearly shown for one- and two-electron ground states in QDs. The variations of the spectra with field are quite different for different dot sizes, and represent magnetic `fingerprints' of the QDs. These phenomena are induced by the negative-ion-electron and electron-electron interactions in QDs.
