摘要：

The electronic states of a parabolic quantum dot in a magnetic field are studied with the inclusion of the spin-orbit interaction. The analytical formulae for the ground state energy of the interacting system are derived. The spin-orbit interaction is shown to introduce new features to the far infrared absorption spectrum, where it leads to the splitting of the two principal modes. The results are compared with the charging experiments by Ashoori et al. and the far infrared absorption measurements by Demel et al.
