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…

Electromagnetic chirality-induced negative refraction with the same amplitude and anti-phase of the two chirality coefficients
Shun-Cai Zhao, Zheng-Dong Liu, Jun Zheng +1
We suggest a scheme of electromagnetic chirality-induced negative refraction utilizing magneto-electric cross coupling in a four-level atomic system. The negative refraction can be…

Manipulative Properties of the Asymmetry Double Quantum Dots via Laser and Gate Voltage
Shun-Cai Zhao, Zheng-Dong Liu
We present the density matrix approach for theoretical description of an asymmetric double quantum dot(QD)system.The results show that the properties of gain,absorption and dispers…
