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...
