Effects of Mirror Dark Matter on Neutron-Star Structure and Tidal Deformability
Jin-Cheng Jiao, Cheng-Ming Li
Mirror dark matter (MDM) can modify neutron-star structure and tidal response through gravitational coupling. In this work, we construct an ordinary-matter equation of state (EOS)…
QCD vacuum pressure and its influence on the equation of state of non-strange quark stars
Cheng-Ming Li, Guang-Hao Yu, Ya-Peng Zhao +4
Solutions of the quark gap equation and the corresponding vacuum pressure are investigated within a modified Nambu-Jona-Lasinio model, which is a basic issue for studying the QCD e…
Two-flavor color superconductivity in a general Nambu-Jona-Lasinio model with color and charge neutrality
Li-Kang Yang, Di-Sheng Fan, Cheng-Ming Li +1
By using a general NJL model including as many interaction channels as possible, and taking into account the constraints imposed by color and charge neutrality, we analyze how the…
Study of hybrid stars with nonstrange quark matter cores
Cheng-Ming Li, He-Rui Zheng, Shu-Yu Zuo +3
In this work, under the hypothesis that quark matter may not be strange (Holdom et al. 2018), we adopt a modification of the coupling constant of the four-quark scalar interaction…
