Abstract
The ground state energy of a parabolically confined quantum dot placed in an external magnetic field is studied taking into account the effects of the Rashba spin–orbit interaction (SOI) and electron–electron interaction. With a simple and physically reasonable model potential for electron–electron interaction term, the problem is solved exactly to second order in the Rashba coupling constant.
► N-electron GaAs quantum dot is studied in the presence of Rashba coupling. ► Exactly soluble model is used for the electron–electron interaction. ► Rashba interaction is included through a unitary transformation. ► Total energy of the system decreases as Rashba coupling increases. ► Rashba interaction reduces the energy with increasing N.
