Left-handedness without absorption in the four-level Y-type atomic medium
Shun-Cai Zhao, Zheng-Dong Liu, Qi-Xuan Wu
In this paper,three external fields interacting with the four-level Y-type atomic system described by the density-matrix approach is investigated .The results show that the left-ha…
2-D isotropic negative refractive index in a N-type four-level atomic system
Shun-Cai Zhao, Qi-Xuan Wu, Kun Ma
2-D(Two-dimensional) isotropic negative refractive index (NRI) is explicitly realized via the orthogonal signal and coupling standing-wave fields coupling the N-type four-level ato…
Effect of Spontaneously Generated Coherence and Detuning on 2D Atom Localization in Two Orthogonal Standing-Wave Fields
Shun-Cai Zhao, Qi-Xuan Wu, Ai-Ling Gong
Two-dimensional (2D) atom localization via the spontaneously generated coherence (SGC) and detunings associated with the probe and standing-wave driving fields in a three-level V-t…
Left-handedness with three zero-absorption windows tuned by the incoherent pumping field and inter-dot tunnelings in a GaAs/AlGaAs triple quantum dots system
Shun-Cai Zhao, Shuang-Ying Zhang, Qi-Xuan Wu +1
Left-handedness with three zero-absorption windows is achieved in a triple-quantum dot (TQD) system. With the typical parameters of a GaAs/AlGaAs heterostructure, the simultaneous…
Negative refraction without absorption via both coherent and incoherent fields in a four-level left-handed atomic system
Shun-Cai Zhao, Zheng-Dong Liu, Qi-Xuan Wu
This paper attempts a probe into negative refraction without absorption by means of an incoherent pump field and a strong coherent field coupling the dense four-level atomic system…
Zero absorption and large negative refractive index in a left-handed four-level atomic media
Shuncai Zhao, Zhengdong Liu, Qixuan Wu
In this paper,we have investigated three external fields interacting with the four-level atomic system described by the density-matrix approach.The atomic system exhibits left-hand…
