Hadronic deuteron polarizability contribution to the Lamb shift in muonic deuterium

Hadronic deuteron polarizability correction to the Lamb shift of muonic deuterium is calculated on the basis of unitary isobar model and modern experimental data on the structure functions of deep inelastic lepton-deuteron scattering and their parameterizations in the resonance and nonresonance regions.

Microwave-to-optical frequency conversion based on the Lamb shift

We consider the microwave-to-optical frequency conversion based on the Lamb shift, fine structure and forbidden transitions. The theory of such a conversion is developed and the efficiency of the microwave-to-optical frequency conversion is calculated. We show that the ratio of the peak power of the induced optical emission to the power of the incident microwave, for a hydrogen atom, can reach 1000000.

μ子氘原子的兰姆位移

Lamb shift in muonic deuterium atom

利用量子电动力学中的三维准势方法，对μ子氘原子的兰姆位移（2 P_{1/2} -2 S_{1/2}）进行了新的研究.考虑了α ^3、α ^4、α ^5和α ^6阶的贡献，计算了真空极化、原子核结构和反冲效应。结果进行了比较，与以前进行的计算。所获得的数值的兰姆位移202.4139毫电子伏可以被认为是一个可靠的估计与即将到来的实验数据进行比较。

质心关联对稠密原子气体中自发发射和兰姆位移的影响

Influence of center-of-mass correlations on spontaneous emission and Lamb shift in dense atomic gases

考虑原子质心坐标的关联，讨论了局域场对原子稠密气体中自发发射速率和兰姆位移的影响。为此，在独立散射近似下，采用虚腔模型计算了介质中的精确延迟传播子。由此产生的原子极化率的变化导致介质响应的修改，其可以与由Morice、Castin和Dalibard [Phys.Rev.A51，3896（1995）]导出的介电函数的局部场校正引起的介质响应具有相同的数量级，但是具有相反的符号。
