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…
Gluon Condensation Signature in the GeV Gamma-Ray Spectra of Pulsars
Ze-Cheng Zou, Yong-Feng Huang, Cheng-Ming Li +2
The accumulation of gluons inside nucleons, i.e., the gluon condensation, may lead to a characteristic broken power-law gamma-ray spectrum in high-energy nucleon collisions. Here w…
Nonextensive effects on QCD chiral phase diagram and baryon-number fluctuations within Polyakov-Nambu-Jona-Lasinio model

Li-Qun Su, Yan Yan, Cheng-Ming Li +2
Based on the properties of uniform nuclear matter at the nuclear saturation density and basic thermodynamic relations, we first re-study the composition of matter on the surface of…

Ya-Peng Zhao, Shu-Yu Zuo, Cheng-Ming Li
We present a nonextensive version of the Polyakov-Nambu-Jona-Lasinio model which is based on the nonextentive statistical mechanics. This new statistics is characterized by a dimen…
Strange quark stars within proper time regularized (2+1)-flavor NJL model

Do the current astronomical observations exclude the existence of non-strange quark stars?
Tong Zhao, Wei Zheng, Fei Wang +4
As is pointed out in a recent work (Phys. Rev. Lett. 120, 222001), quark matter may not be strange. Inspired by this argument, we use a new self-consistent mean field approximation…
