论文摘要
我们提出了一种方法，可以在驱动的空腔分子系统中基于量子相关功能来实现手性分子的映异义，其中手性分子与量化的腔场和两个经典的光场耦合以形成环状三级模型。根据手性分子的电 - 偶极转变矩的固有特性，在左手和右手的手性分子的环状三级模型的整体相位上存在$π$的相差。因此，相关函数取决于这个整体阶段，并且取决于手性。分析和数值结果表明，可以通过检测量子相关函数来区分左手和右手的手性分子。我们的工作为歧视分子手性的有前途的途径开辟了道路，这是药理学和生物化学中极为重要的任务。
We propose a method to realize enantiodiscrimination of chiral molecules based on quantum correlation function in a driven cavity-molecule system, where the chiral molecule is coupled with a quantized cavity field and two classical light fields to form a cyclic three-level model. According to the inherent properties of electric-dipole transition moments of chiral molecules, there is a $π$-phase difference in the overall phase of the cyclic three-level model for the left- and right-handed chiral molecules. Thus, the correlation function depends on this overall phase and is chirality-dependent. The analytical and numerical results indicate that the left- and right-handed chiral molecules can be discriminated by detecting quantum correlation function. Our work opens up a promising route to discriminate molecular chirality, which is an extremely important task in pharmacology and biochemistry.
