A possible origin of the Galactic Center magnetar SGR 1745–2900
《Research in Astronomy and Astrophysics》2017年第6期47-54,共8页Quan Cheng Shuang-Nan Zhang Xiao-Ping Zheng 
supported by the National Natural Science Foundation of China(Grant Nos.11133002 and 11178001)
Since there is a large population of massive O/B stars and putative neutron stars （NSs） located in the vicinity of the Galactic Center （GC）, intermediate-mass X-ray binaries （IMXBs） constituted by an NS and a B-...

Dispersion relation of excitation mode in spin-polarized Fermi gas
《Chinese Physics B》2012年第3期80-84,共5页刘可 陈继胜 
Project supported by the National Natural Science Foundation of China (Grant No. 10875050 and 11178001)
We study the dispersion relation of the excitation mode in a spin-polarized Fermi gas. In the frame of the imaginarytime finite temperature field theory, the polarization tensor is calculated by taking the random phas...
