论文摘要
为了获得夸克物质状态和构建杂化恒星的方程，我们计算了三种味道Nambu-Jona-lasinio模型中的热力学潜力，包括张量型四点相互作用和Kobayashi-Maskawa-Maskawa-hooft-nohoft交互作用。为了构建杂种恒星，有必要在系统上施加β-均衡状并充电中立条件。结果表明，张量的冷凝相物出现在较大的化学势。在张量冷凝物存在的可能性下，估计了杂交恒星半径和质量之间的关系。
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 beta-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.
