摘要:

本文从自下而上的爱因斯坦-麦克斯韦-膨胀子全息模型出发,给出了热稠密强相互作用QCD物质的物态方程和跃迁线的新结果。我们通过实施新的数值方法将全息黑洞解映射到QCD相图上,大大扩展了该模型中重子密度的覆盖范围。我们还能够获得,为第一次,一级相变线在一个广泛的区域的相图。最新的晶格结果的QCD热力学的比较也被提出。

英文摘要:

We present new results on the equation of state and transition line of hot and dense strongly interacting QCD matter, obtained from a bottom-up Einstein-Maxwell-Dilaton holographic model. We considerably expand the previous coverage in baryon densities in this model by implementing new numerical methods to map the holographic black hole solutions onto the QCD phase diagram. We are also able to obtain, for the first time, the first-order phase transition line in a wide region of the phase diagram. Comparisons with the most recent lattice results for the QCD thermodynamics are also presented.
