We demonstrate here that the dipole-allowed optical absorption spectrum of a parabolic quantum dot subjected to an external magnetic field reflects the interelectron interaction effects when the spin-orbit (SO) interaction is also taken into account. We have investigated the energy spectra and the dipole-allowed transition energies for up to four interacting electrons parabolically confined, and have uncovered several novel effects in those spectra that are solely due to the SO interaction.
我们在此证明，当考虑自旋轨道（SO）相互作用时，处于外部磁场中的抛物量子点的偶极允许光学吸收光谱反映了电子间的相互作用效应。我们研究了抛物限制下多达四个相互作用电子的能谱和偶极允许跃迁能量，并在这些光谱中发现了一些仅由SO相互作用引起的新效应。
