摘要
研究磁场中束缚极化子声子平均数的性质,采用线性组合算符和变分法讨论了磁场中强、弱耦合极化子的振动频率和光学声子平均数与磁场B和库仑势的关系,以RbCl晶体为例进行了数值计算,结果表明:强耦合束缚磁极化子的振动频率λ和声子平均数N随磁场B和库仑势的增加而增大.
In this paper ,the properties of the mean number of phonons of the bound polaron in a magnetic field is studied .The relation of vibrational frequency and mean number of phonons of the both weak-and strong-coupling bound magnetopolaron to the magnetic field and Coulomb potential are discussed by using linear combination operator and unitary transformation methods.Numerical calculation for RbCl crystal,as an example ,were performed and the result illustrates that the vibrational frequency and the mean number of phonon of strong-coupling magnetopolaron will increase with increasing magnetic field and Coulomb potential.
