论文摘要
从理论上讲，我们引入了一种在手性分子的外围混合物上执行拉姆西光谱的方案，同时提取了左手和右手分子的过渡频率，称为映异构体。通过采用对映体特异性频率之间的差异，我们隔离了弱力违规（PV）移位，这预计会破坏对映异构体之间的对称性。为了执行该方案，我们设计了一个脉冲序列，该脉冲序列使用电动 - 偶极矩成分的三级产品的映体依赖性符号在三级系统中创建对映体特异性斜位。延迟的第二脉冲序列完成了拉姆西询问序列，从而使每个对映体通过单独的量子状态的过渡恢复了相位演变。我们的技术克服了在对映 - 纯样品之间进行交替以测量PV的需求。我们描述了所提出的精确测量方法的优势。
We theoretically introduce a scheme to perform Ramsey spectroscopy on a racemic mixture of chiral molecules, simultaneously extracting the transition frequencies of the left- and right-handed molecules, known as enantiomers. By taking the difference between the enantio-specific frequencies, we isolate the weak force parity violation (PV) shift, which is predicted to break the symmetry between enantiomers. To perform the scheme, we design a pulse sequence that creates enantio-specific superpositions in a three-level system using the enantiomer-dependent sign of the electric-dipole moment components' triple product. A delayed second pulse sequence completes the Ramsey interrogation sequence, enabling readout of the phase evolution for each enantiomer's transition through a separate quantum state. Our technique overcomes the need to alternate between enantio-pure samples to measure PV. We describe the advantages of the proposed method for precision metrology.
