高密度Sakai-Sugimoto膜系

Sakai-Sugimoto Brane System at High Density

Daiske Yamada

摘要:

在弱耦合区研究了高夸克密度下Sakai-Sugimoto模型的D4-D8膜系统。我们证明了色超导相(对于Nc~3)或手征密度波(对于Nc->无穷大)在很大的化学势下消失,或者等价地在模型所具有的很大的紧化维数下消失。我们还评论的前景,在强耦合制度,随着QCD相图。

英文摘要:

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.
