宇宙学氢复合时代的电磁感应透明研究

Investigation of the electromagnetically induced transparency in era of cosmological hydrogen recombination

D. Solovyev, V. K. Dubrovich, G. Plunien

摘要:

对宇宙微波背景形成过程的研究是目前最实际的问题之一。本文分析了氢原子对外光场的响应。场的特征是通过宇宙复合时代的条件来定义的。用三能级原子近似描述了“原子-场”相互作用。结果表明,在这种情况下发生了电磁感应透明现象。考虑EIT现象,有必要更新天体物理学描述的过程中的宇宙微波背景的形成,特别是索博列夫逃逸概率。发现Sobolev逃逸概率定义中光学深度的附加项约为1%。

英文摘要:

Investigation of the cosmic microwave background formation processes is one of the most actual problem at present time. In this paper we analyze the response of the hydrogen atom to the external photon fields. Field characteristics are defined via conditions corresponding to the recombination era of universe. Approximation of three-level atom is used to describe the "atom - fields" interaction. It is found that the phenomena of the electromagnetically induced transparancy takes place in this case. Consideration of EIT phenomena makes it necessary to update astrophysical description of the processes of the cosmic microwave background formation and, in particular, Sobolev escape probability. Additional terms to the optical depth in definition of Sobolev escape probability on the level about 1% are found.
