Abstract
By using an exact numerical diagonalization scheme, we studied the low-lyin g spectrum of a magnetopolaron quantum dot with a confined parabolic potent ial in the presence of a Coulomb impurity at the center. Continuous ground- state energy transitions induced by the magnetic field are reported. Furthe rmore, the effect of different electron-LO phonon interaction strengths on the energy spectrum has been predicted, (C) 1999 Elsevier Science Ltd. All rights reserved.
