Superluminal light attenuated by strong dispersion of complex refractive index
《Chinese Physics B》2016年第2期477-481,共5页Abdurahman Ahmed Yonis Vadim Nickolaevich Mal'nev Belayneh Mesfin Ali 
The propagation of narrow packets of electromagnetic waves(EMWs) in frequency dispersive medium with the consideration of the complex refractive index is studied. It is shown that counting in the dispersion of the c...

Role of incoherent pumping and Er^(3+) ion concentration on subluminal and superluminal light propagation in Er^(3+)-doped YAG crystal
《Chinese Physics B》2015年第1期269-274,共6页Seyyed Hossein Asadpour H.Rahimpour Soleimani 
We study the absorption-dispersion process and group index of weak probe field in a four-level Er^3+:YAG crystal.We find that the Er^3+ion concentration and incoherent pumping field can influence the absorption-dis...

Controlling group velocity in a superconductive quantum circuit
《Chinese Physics B》2012年第10期274-278,共5页邱田会 杨国建 
Project supported by the National Natural Science Foundation of China (Grant No. 111174040);the Fundamental Research Funds for the Central Universities
We investigate the controllable group velocity of a microwave probe field in a superconductive quantum circuit(SQC) pumped by microwave fields,and the use of such a SQC function as an artificial Λ-type three-level ...

Subluminal to superluminal light propagation in a V-type three-level atomic system interacting with squeezed vacuum
《Chinese Physics B》2012年第2期243-249,共7页Zhang Qin Qu Guang-Hui Tang Yuan-He Jin Kang Ji Wei-Li 
supported by the National Natural Science Foundation of China (Grant No.10874138)
We study the light propagation properties in a V-type three-level atomic system interacting with two independent broadband squeezed baths. Using the graphic method, the dependences of the absorption and the dispersion...

Influence of Doppler-broadening on absorption-dispersion properties in a resonant coherent medium
《Chinese Physics B》2005年第12期2496-2502,共7页徐卫华 高锦岳 
We investigate the influence of Doppler broadening on absorption-dispersion properties in a four-level atomic system that can evolve from a normal dispersion to an anomalous dispersion. Our results show that the absor...
