Abstract
A coupled quantum dot system has been studied by numerical diagonaliza tion of the Hamiltonian. Discontinuous ground-state transitions induce d by an external magnetic field have been predicted. Series of magic n umbers of angular momentum which minimize the ground-state electron-el ectron interaction energy have been discovered. Theoretical explanatio ns derived from the first principles have been formulated.
