In this paper, we discuss the statistical properties of London-modified coherent states that were introduced in order to build up a resolution of the identity for London coherent states. The resolution to the identity is realized by the application of an operator to the London cohrent states. Next we find the Mandel-Q parameter that shows that there exist sub-Poissonian behaviour for a large interval of amplitudes, look at their behaviour in phase space through the Husimi-Q function and study their interaction with a two-level atom. We show that their oscillating photon distributions are responsible for the ringing revival behaviour shown by the atomic inversion.

伦敦修改的相干态:统计性质和与两个原子的相互作用

在本文中,我们讨论引入伦敦修改的相干态的统计属性,以建立对伦敦相干态身份的解析。身份的解析是通过将操作员应用于伦敦各个州来实现的。接下来,我们找到Mandel-Q参数,该参数表明存在一个较大的幅度间隔的次Poissonian行为,通过Husimi-Q函数查看它们在相空间中的行为,并研究它们与两级原子的相互作用。我们表明,它们的振荡光子分布是原子反演所显示的振铃复兴行为的原因。
