计算并详细研究了嵌入57Fe层的x射线腔qed装置内的场重分布。从基态到上修饰态的两次跃迁之间的相消干涉导致腔模不能被驱动。所以当核系综共振时，场强非常弱。此外，还发现共振核层可以像镜子一样起到反射层的作用，并且可以切割腔体的尺寸，从而破坏导模。为了支持这一想法，我们采用57Fe薄膜作为谐振腔的底镜层，在谐振腔中只能在共振能量处形成引导模式。从这一角度出发，回顾了基于x射线腔-核系综的电致透明结构，并给出了场重分布的现象学自洽分析。
The field redistribution inside an X-ray cavity-QED setup with an embedded 57Fe layer is calculated and studied in detail. The destructive interference between two transitions from the ground state to the two upper dressed states causes that the cavity mode can not be driven. So the field intensity is very weak when the nuclear ensemble is resonant. Moreover, It is found that the resonant nuclear layer can play a role of reflective layer like a mirror and cut the size of the cavity, which will destroy the guided mode. To support this idea, we employ the 57Fe film as the bottom mirror layer of the cavity where a guided mode can only be formed at the resonant energy. Following this perspective, the electromagnetically induced transparency structure based on X-ray cavity-QED setup with nuclear ensemble is reviewed and a phenomenologically self-consistent analysis for the field redistribution is presented.
