摘要：
本文对四能级原子介质中电磁手性诱导的负折射率进行了代数分析。通过数学分析其一种圆偏振的复折射率的辐角，发现当该辐角位于笛卡尔坐标系的第二象限时，无需同时具有负介电常数和负磁导率即可获得负折射率，且探针场耦合到原子能级中两个相等的跃迁频率并非必需。这无疑降低了量子光学获得负折射率的苛刻条件。作为应用，我们的方案可能提供一种通过电磁手性诱导获得负折射率的新途径。abstract_cn
英文摘要：
This paper presents a algebraic analysis of electromagnetic chirality-induced negative refractive index in a four-level atomic medium. According to analyze mathematically its argument of the complex refractive index for one circular polarization, it found that the negative refractive index without simultaneously negative permittivity and permeability can be obtained when the argument is in the second quadrant of the cartesian coordinate system, and that the probe field coupling to two equal transition frequencies in the atomic level doesn't require. This undoubtedly reduced stringent conditions to negative refractive index by quantum optics. As an application, our scheme may possibly give a novel approach to obtain negative refractive index by electromagnetic chirality-inducing.
