Electronic spectra of two interacting electrons confined in a quantum dot in a magnetic field

Abstract

The energy spectrum of two interacting electrons, confined in a parabolic quantum dot, presented in a magnetic field, is obtained by using the shifted 1/D expansion method. The effects of electron-electron interaction and quantum dot size on the energy levels are studied. Interesting features of the quantum dot spectra such as the energy level crossings and the removal of the degeneracy are explained. Based on comparisons, our calculated results are in very good agreement with numerical ones.
