We study the confinement/deconfinement transition of QCD matter for a quark-gluon plasma at finite density using AdS/QCD duality. In order to determine the critical temperature and its dependence on the quark chemical potential, the semi-classical Hawking-Page approach is considered for a charged AdS black hole. The result obtained is consistent with the QCD phase diagram, with the critical temperature decreasing as the chemical potential increases. Using the soft wall holographic model, the value of quark density in which the phase transition occurs at zero temperature is estimated. For higher densities the QCD matter is deconfined, independent of the temperature.

有限密度全息 QCD 中的霍金-佩奇跃迁


我们使用 AdS/QCD 对偶性研究有限密度夸克-胶子等离子体的 QCD 物质的限制/解除限制转变。为了确定临界温度及其对夸克化学势的依赖性，针对带电 AdS 黑洞考虑了半经典霍金-佩奇方法。所得结果与QCD相图一致，临界温度随着化学势的增加而降低。利用软壁全息模型，估计了零温度下发生相变的夸克密度值。对于更高的密度，QCD 物质被解除限制，与温度无关。
