量子线中强耦合束缚磁极化子的电场效应

采用线性组合算符和幺正变换相结合方法研究了电场和温度对抛物量子线中强耦合束缚磁极化子性质的影响。计算了在电场和温度影响下抛物量子线中强耦合束缚磁极化子的基态能量、平均声子数和振动频率。数值计算结果表明：量子线中强耦合束缚磁极化子的基态能量随约束强度、回旋共振频率和电场强度的增强而增大，随耦合强度的增大和温度的上升而减小；平均声子数随回旋共振频率、约束强度和温度的增大而增加；振动频率随回旋共振频率的增大而增大，同时也随约束强度的增大而增大。

Electric Field Effect of Strong-coupling Bound Megnetpolaron in Quantum Wires

The influences of electric field and temperature on properties of strong-coupling bound megnetpolaron in parabolic quantum wires are studied by using of the linear combination operator and the unitary transformation methods. The relations of the ground state energy, the mean number of megnetphonon and the vibrational frequency in parabolic quantum wires with the confinement strength, the cyclotron resonance frequency and electric field were calculated. The numerical results show that the ground state energy will increase with the confinement strength, the cyclotron resonance frequency and electric field, however, it will decrease with increasing of the temperature and the coupling strength. The mean number of phonon is a increasing function of the temperature and the confinement strength and the cyclotron resonance frequency. The variation frequency will increase with increasing of the cyclotron resonance frequency and the confinement strength.
