| 摘 要： | 在LLP正则变换基础之上，引入线性组合算符，选取一个包含双声子关联效应的基态计算库仑束缚磁极化子的基态能量．计算表明，考虑声子关联效应时，束缚磁极化子的基态能量降低．双声子关联效应所对应的能量与耦合常数的二次方密切相关． |
| 关 键 词： | 极化子 波函数 基态能量 声子关联 |

| Abstract: | Based on LLP canonical transformation,a different polaron ground-state which includes the two-phonon correlation is adopted to calculate the ground-state energy of coulomb bound magnetopolaron. The calculation indicates that the energy created by two-phonon correlation is relative to coupling constant. The result shows that ground-state energy is lowered taking two-phonon correlation into account. |
| Keywords: | polaron wave function ground-state energy two-phonon correlation |
