The effective Hamiltonian of surface magnetopolaron in polar crystals was derived by using the linear combination operator and perturbation method. The influence of the interaction between phonons of different wave vectors in the recoil process on the induced potential of the surface magnetopolaron was discussed. 表面磁极化子 有效哈密顿量 诱生势 surface magnetopolaron effective Hamiltonian induced potential 中国科学院激发态物理开放研究实验室科学基金 1997-11-03 1998-11-30 2021-03-18 4 19
