【摘要】 本文采用线性组合算符和幺正变换相结合方法研究自旋和温度对量子线中强耦合束缚磁极化子性质的影响.计算了在自旋和温度影响下量子线中强耦合束缚磁极化子的振动频率、基态能量和平均声子数.计算表明,在自旋和温度影响下振动频率随温度和库仑束缚势的增大而加快;基态能量随温度和回旋频率的的增加而变大,并在自旋作用下基态能量曲线分裂为自旋向上,向下两条;平均声子数也随温度的升高而增多.更多还原

【Abstract】 The properties of bound magnetpolaron,which is strong coupled to LO-phonon in quantum wire induced,by influence of spin and temperature were studied by using liner combination operator and unitary transformation method.Which derived strong-coupling bound magnetopolarn’s vibrational frequency,ground state energy and the mean number of phonons.The results illustrate when the electron spin and temperatue were considered,the vibrational frequency is an increasing function of temperatue and the Coulomb bound potential;the ground state energy splits into two energy which are spin up and spin down energy and is an increasing function of temperatue and the cyclotron frequency;the mean number of phonos is an increasing function of temperatue.更多还原
