用少体物理的方法,研究了磁场中量子盘三电子系统极化态的基态能量和盘厚之间的关系.随着量子盘厚度的增加,三电子系统中的幻数角动量态即分数量子霍耳效应态将不再出现.结果还表明,幻数角动量消失的量子盘厚度随磁场强度的增加而减小.By use of the method of few-body physics, we study the relations between the energy of ground state and the thickness of three-electron quantum disk in a magnetic field. As the thickness increases, the magic number angular momentum states of three-electron(i.e., the states of fractional quantum Hall effect) will be destroyed. The results show the thicknesses of quantum disks whose magic number angular momentum is destroyed decrease as the magnetic fields increase.
