摘　　要：在构造含有经常被忽略的反磁项系统哈密顿量基础上,利用微扰理论计算系统的缀饰基态二阶能移,得到Casimir-Polder力的解析表达式.通过数值分析,讨论了反磁项对力的性质及大小的影响.结果表明:尽管增加反磁项并没有使Casimir-Polder力的性质发生变化,但反磁项增大了力的大小.其结果与方法可以用于研究其他光学腔中的Casimir-Polder力.Based on the interaction Hamiltonian with the negligible diamagnetic term,the perturbation theory is used to calculate the second-order energy shift of the system s embellished ground state,and the analytical expression of the Casimir-Polder force is obtained.Through numerical analysis,the influence of diamagnetic on the nature and size of the force is discussed.Studies have shown that although the addition of the diamagnetic term does not change the properties of the Casimir-Polder force,the diamagnetic term increases the force.The results and methods can be used to study the Casimir-Polder forces in other optical cavities.
