Ca+-Pyridine络合物的光解反应

使用反射式飞行时间质谱仪,得到 Ca~ -pyridine 络合物在412～ 690nm 的光解谱.从谱图可见,反应有两个通道,一个是 Ca~ 与 pyridine 分子解离开的非反应淬灭过程,这个通道在所有波段都有,且占优势；生成产物 Ca~ NH_2的通道不仅所占比例小,且在530～590nm 波段关闭. 作为激光波长函数的 Action spectrum 显示出明显的峰,对应于络合物的跃迁.反应的分支比也支持了光解谱图的结论.     

Numerical Study on Left-Handed Materials Made of Ferrite and Metallic Wires

Due to coupling effect, we show that it is difficult to realize the left-handed material by placing metallic wires directly into a ferrite matrix. However by introducing an insulating material round the metallic wires to decouple the direct interaction between the metallic wire and ferrite matrix, we have proposed two microstructures, which are shown by numerical simulation to have negative refractive indexes. The influence of microstructure on the transmission property is also examined.

Realization of Greenberg-Horne-Zeilinger （GHZ） and W Entangled States with Multiple Superconducting Quantum-Interference Device Qubits in Cavity QED

An alternative scheme is proposed for generating the Greenberg-Horne-Zeilinger （GHZ） and W types of the entangled states with multiple superconducting quantum-interference device （SQUID） qubits in a single-mode microwave cavity field. In this scheme, there is no transfer of quantum information between the SQUIDs and the cavity, the cavity is always in the vacuum and thus the requirement on the quality of cavity is greatly loosened. In addition, during the process of the generation of the W entangled state, the present method does not involve a real excitation of intermediate levels. Thus, decoherence due to energy relaxation of intermediate levels is minimized.
