QHC18

Abstract

This table corresponds to the zero temperature and beta-equilibrium unified EoS by Baym et al. [ BHK_2018]. The EoS are divided into four distinct domains: the crust, nuclear liquid, hadron-quark crossover, and quark matter domains. For each domain we assign an equation of state as

Crust : Togashi EoS [TNTYST_17]
Nuclear liquid : APR98 EoS [APRP_1998]
Crossover : QHC18 [BHK_2018]
Quark matter : QHC18 [BHK_2018]

The quark matter EoS (including up-, down-, and strange-quarks) in the QHC18 was calculated using the NJL model within the mean field approximation. As variable parameters, we choose g_V and H which quantify the strength of the repulsive density-density interaction and the attractive paring-interaction between quarks, respectively. We chose (g_V, H)=(0.80,1.50)G which is compatible with hadron physics. The QHC18 satisfies the empirical constraints from neutron stars as well as the causality and thermodynamic consistency.
