To obtain the equation of state of quark matter and construct hybrid stars, we calculate the thermodynamic potential in the three-flavor Nambu–Jona-Lasinio model including the tensor-type four-point interaction and the Kobayashi–Maskawa–’t Hooft interaction. To construct the hybrid stars, it is necessary to impose the [Formula: see text] equilibrium and charge neutrality conditions on the system. It is shown that tensor condensed phases appear at large chemical potential. Under the possibility of the existence of the tensor condensates, the relationship between the radius and mass of hybrid stars is estimated.

来自具有两种张量凝聚体的三味 NJL 模型的混合星

为了获得夸克物质的状态方程并构建混合星，我们计算了包括张量型四点相互作用和小林-Maskawa-'t Hooft相互作用的三味Nambu-Jona-Lasinio模型中的热力学势。为了构建混合星，需要对系统施加[公式：见正文]平衡和电荷中性条件。结果表明，张量凝聚相出现在大的化学势下。在张量凝聚体存在的可能性下，估计了混合星的半径与质量的关系。
