摘要
文章采用改进的线性组合算符和幺正变换的方法研究了自旋对量子线中强耦合磁极化子性质的影响,导出了量子线中强耦合磁极化子的振动频率、基态能量、有效质量和声子平均数.结果表明:当考虑自旋时,量子线中磁极化子的基态能量随耦合强度的增大而减小,并且分裂为两个分支.所以电子自旋对基态能量的影响不能忽略.
The spin which influences the properties of strong coupling magnetopolaron is studied using the improved linear combination operator and unitary transformation method in quantum wire.The strong coupling magnetopolaron vi-bration frequency,ground state energy,effective mass and the mean number of phonos are calculated. Our results indi-cate the ground-state energy of the magnetopolaron decreases with increasing coupling strength and divides into two branches considering the spin.The electron spin is important to the influence of the ground state energy.
