摘要：

本文研究了有限温度全息QCD（Sakai-Sugimoto）模型在外电场和磁场中的非对易形变，并讨论了非对易性对与重子数电流有关的导体-绝缘体相变性质的影响。虽然规范理论的非对易变形并不改变相对于重子数电流的相结构，但在导体-保险子相变中的相变温度$T_{c}$、相变电场$e_{c}$和磁场$b_{c}$依赖于非对易性参数$θ$。也就是说，空间坐标的非对易性对导体-保险层相变的相图形状有影响。另一方面，非对易性参数的允许范围可以由运动常数的实际条件来限制。

英文摘要：

We consider the noncommutative deformation of the finite temperature holographic QCD (Sakai--Sugimoto) model in external electric and magnetic field and evaluate the effect of the noncommutaivity on the properties of the conductor-insulator phase transition associated with a baryon number current. Although the noncommutative deformation of the gauge theory does not change the phase structure with respect to the baryon number current, the transition temperature $T_{c}$, the transition electric field $e_{c}$ and magnetic field $b_{c}$ in the conductor-insurator phase transition depend on the noncommutativity parameter $θ$. Namely, the noncommutativity of space coordinates has an influence on the shape of the phase diagram for the conductor-insurator phase transition. On the other hand, the allowed range of the noncommutativity parameter can be restricted by the reality condition of the constants of motion.
