Three-dimensional equation of state extension of quark matter in Fermi-liquid theory
Zhenyu Zhu, Shuai Zha, Sophia Han
The cold, dense matter equation of state (EoS) determines crucial global properties of neutron stars (NSs), including the mass, radius and tidal deformability. However, a one-dimen…

Equation of State of Decompressed Quark Matter, and Observational Signatures of Quark-Star Mergers
Zhiqiang Miao, Zhenyu Zhu, Dong Lai
Quark stars are challenging to confirm or exclude observationally because they can have similar masses and radii as neutron stars. By performing the first calculation of the non-eq…
