Left-Handed Material in Five-Level System Based on the Effect of Spontaneously Generated Coherence

Xiang An Yan, Li Qiang Wang

We propose a scheme for realizing negative refractive index in a multilevel atomic system. The theoretical modeling has been done using density matrix approach in which the spontaneously generated coherence (SGC) is also induced. It is shown that the negative refractive index can be obtained on the effect of quantum coherence. The parameters () quantifying left-handedness in the system become more negative if the SGC is defined in the appropriate value. Furthermore, left-handed material with reduced absorption is possible by choosing appropriate parameters.

Negative Refractive Index in a Multilevel Atomic Medium

Kariman I. Osman, Amitabh Joshi

Possibility of generating negative refractive index in a multilevel atomic medium interacting with four electromagnetic fields is discussed. The spontaneously generated coherence arising due to the nearby decaying levels produces such negative refractive index.
