$\mathcal{P}$，$\mathcal{T}$ -奇数法拉第旋转在分子束内腔吸收光谱中作为一种可能的方法来提高寻找自然界中的时间反射非不变效应的灵敏度
$\mathcal{P}$, $\mathcal{T}$-odd Faraday rotation in intracavity absorption spectroscopy with molecular beam as a possible way to improve the sensitivity of the search for the time reflection noninvariant effects in nature
摘要：
目前对违反电子电偶极矩（$e$ EDM）的空间宇称（$\mathcal{P}$）和时间反射不变性（$\mathcal{T}$）的约束是基于使用ThO分子在外部电场中对电子自旋进动的观察。我们提出了另一种方法：观察的$\mathcal{P}$，~ $\mathcal{T}$奇法拉第效应在一个外部电场使用的腔增强偏振计划结合分子束穿过腔。我们对PbF和ThO分子束实验的理论模拟表明，目前对$e$ EDM的约束原则上可以提高几个数量级。
英文摘要：
The present constraint on the space parity ($\mathcal{P}$) and time reflection invariance ($\mathcal{T}$) violating electron electric dipole moment ($e$EDM) is based on the observation of the electron spin precession in an external electric field using the ThO molecule. We propose an alternative approach: observation of the $\mathcal{P}$,~$\mathcal{T}$-odd Faraday effect in an external electric field using the cavity-enhanced polarimetric scheme in combination with a molecular beam crossing the cavity. Our theoretical simulation of the proposed experiment with the PbF and ThO molecular beams shows that the present constraint on the $e$EDM in principle can be improved by a few orders of magnitude.
