在有效质量近似下,使用少体物理的方法,计算了在不同大小约束势情况下二维量子点三电子系统的自旋极化态的能谱.结果显示幻数角动量是否出现,主要取决于量子力学对称性、约束势大小及磁场的强度.Within the effective mass approximation, the energy spectra of the three-electron system in two-dimensional quantum dots subjected to different confinement potential are calculated by using the method of few-body physics. The results show that the appearance of magic angular momentum arises from the quantum mechanical symmetry, the size of confinement potential and the strength of magnetic field.
