The influence of Rashba effect on the properties of bound magnetopolaron in quantum wire

采用改进的线性组合算符和幺正变换相结合的方法研究了Rashba效应对抛物量子线中强耦合束缚磁极化子性质的影响.计算了抛物量子线中强耦合束缚磁极化子的有效质量和振动频率,对Rb Cl材料的数值计算结果表明:量子线中强耦合束缚磁极化子的振动频率随受限强度和回旋频率的增加而增大;有效质量与磁极化子的受限强度、回旋频率和电子面密度有关,在Rashba效应影响下有效质量随上述各量的变化曲线都发生了分裂.

The influences of Rashba effect on the properties of strong -coupling bound magnetopolaron in quan-tum wire are studied by using the improved linear combination operator and the unitary transformation methods . The effective mass and the vibrational frequency are calculated .Numerical calculations for RbCl crystal are per-formed and the results show that the Rashba effect makes the effective mass of the bound magnetpolaron split into two branchs , whereas the vibration frequency λof polaron will increase with the increases of the confinement strength and the cyclotron frequency .
