论文摘要
在中子恒星内实现的密度和温度下，确定量子染色体动力学（QCD）的相结构及其状态方程（EOS）是一个长期的开放问题。全息V-QCD框架为密集和热QCD的EOS提供了一个模型，该模型描述了密集的Baryonic和Quark物质阶段之间的解料相变。我们在完全一般的相对论流体动力学（GRHD）模拟中使用该模型来研究夸克物质的形成以及与有史以来第一个观察到的中子星合并事件GW170817相似的二元系统的发射引力波信号。
Determining the phase structure of Quantum Chromodynamics (QCD) and its Equation of State (EOS) at densities and temperatures realized inside neutron stars and their mergers is a long-standing open problem. The holographic V-QCD framework provides a model for the EOS of dense and hot QCD, which describes the deconfinement phase transition between a dense baryonic and a quark matter phase. We use this model in fully general relativistic hydrodynamic (GRHD) simulations to study the formation of quark matter and the emitted gravitational wave signal of binary systems that are similar to the first ever observed neutron star merger event GW170817.
