采用Huybrenchts线性组合算符和Lee—Low—Pines(LLP)变换方法,研究了磁场和库仑场对抛物量子线中强耦合极化子激发态性质的影响,推导出了抛物量子线中强耦合束缚磁极化子的第一内部激发态能量、激发能量和振动频率。数值计算结果表明:抛物量子线中强耦合束缚磁极化子的第一内部激发态能量和激发能量及振动频率均随约束强度、回旋频率的增加而增大;第一内部激发态能量随库仑束缚势的增加而减少,激发能量和振动频率随库仑束缚势的增加而增强。
With Huybrenchts's linear combination operator and the Lee-Low-Pines(LLP) transformation methods, properties of excited state of strong-coupling magnetopolaron in parabolic quantum wires are studied. The relations of the first internal excited energy, excitation energy and vibration frequency in parabolic quantum wires with the Coulomb bound potential, confinement strength and cyclotron frequency axe presented. The numerical results indicate that the first internal excited energy, excitation energy and vibration frequency increase with increasing of confinement strength and the cyclotron frequency. The excitation energy and vibration frequency are increasing functions of the Coulomb bound potential, and the first internal excited energy decreases with increasing of the Coulomb bound potential.
