摘要 研究库仑场中束缚光学极化子的性质 ,采用线性组合算符和么正变换方法计算了强弱耦合情形束缚光学极化子的基态和第一激发态能量 .计算结果表明 :库仑场使束缚光学极化子的基态和第一激发态能量的绝对值变大 ,激发能量变大 .不同离子晶体或不同极化材料中 。 In this paper,the properties of the bound optical polaron in Coulomb potential is studied,which is valid for the whole range of the electron-phonon coupling.The energy of the ground state and of the first excited state of the bound optical polaron is calculated for different values of the electro-phonon coupling using linear combination operator and unitary transformation methods.
