| Abstract: | By using the method of few-body physics, we study the relations between the energy of ground states and angular momentum of the four-electron systems in two-dimensional quantum dots in magnetic fields. The influences of the magnetic field and confined potential on ground states of the four-electron systems have been numerically calculated. The numerical results show that the quantum mechanical symmetry is the origin of magic numbers. |
