In this paper, using the path integral Monte Carlo (PIMC) simulation method, we have calculated the total energy of a two-dimensional parabolic quantum dot (2D-PQD). We have also calculated electron density in the QDs under different conditions. Furthermore, we have studied the effects of temperature, number of electrons confined in a QD, electron-electron interaction and magnetic field on the total energy of the dots. We have demonstrated the sequence by which the Wigner molecule shells are occupied, for a QD containing up to 20 electrons.
