For quantum systems with broken parities, a transition can appear for any two different states, and cyclic transition structures can be generated for the lowest three levels. Based on these loop transitions, we discuss how to achieve high-precision localization effects for physical objects with broken parities, i.e . chiral molecules and asymmetric quantum wells. In a Δ-type three-level system interacting simultaneously with three external fields, one of which is a standing-wave field, the absorption spectrum carries information about the position of the objects. Moreover, we can achieve 100% probability of finding the objects at certain positions by choosing appropriate parameters. In addition, we present two possible implementations of the suggested scheme in a system comprising a mixture of left- and right-handed chiral molecules and asymmetric quantum wells and show how the phase-sensitive localization effect can be used to discriminate between enantiomeric molecules.<...

具有奇偶校验的量子系统中的本地化

对于奇偶校验破损的量子系统，对于任何两个不同的状态都可能出现跃迁，并且对于最低的三个能级会生成循环跃迁结构。在这些循环过渡的基础上，我们讨论了如何对具有奇偶校验（即）的物理对象实现高精度的定位效果。手性分子和不对称量子阱。在与三个外部场（其中之一是驻波场）同时相互作用的Δ型三能级系统中，吸收光谱会携带有关物体位置的信息。此外，通过选择适当的参数，我们可以获得在特定位置找到对象的100％概率。此外，
