在弱耦合状态下研究了高夸克密度下 Sakai-Sugimoto 模型的 D4-D8 膜系统。我们表明，颜色超导相（对于 Nc~3）或手性密度波（对于 Nc->无穷大）在非常大的化学势下消失，或者等效地在模型拥有的非常大的紧致维数下消失。我们还结合 QCD 相图对强耦合机制的前景进行了评论。
The D4-D8 brane system of Sakai-Sugimoto model at high quark density is studied in the weak coupling regime. We show that the color superconducting phase (for Nc~3) or the chiral density wave (for Nc->infinity) disappears at very large chemical potential, or equivalently at very large compactified dimension that the model possesses. We also comment on the prospects in the strong coupling regime along with the QCD phase diagram.
