We study the homogenous quenching processes in a holographic s+p model with reentrant phase transitions. We first realize the reentrant phase transition in the holographic model in probe limit and draw the phase diagram. Next, we compare the time evolution of the two condensates in two groups of numerical quenching experiments across the reentrant region, with different quenching speed as well as different width of the reentrant region, respectively. We also study the dynamical competition between the two orders in quenching processes from the normal phase to the superconductor phase.

本文利用全息规范/引力对偶理论，系统地计算了强耦合各向异性等离子体在外加磁场作用下的喷注猝灭参数。磁场打破了空间旋转对称性从$SO(3)$到$SO(2)$，导致存在多个各向异性射流淬火参数，这是在这里评估两个完全不同的全息设置。其中一个对应于强耦合$\mathcal{N} = 4$ Super Yang-Mills等离子体在外磁场作用下的自上而下的形变，另一个对应于高能外围重离子碰撞的自下而上的Einstein-Maxwell-Dilaton模型，因为它能够提供$(2+1)$定量描述，用零和非零磁场下的物理夸克质量来格点量子色动力学热力学。我发现这两个模型的所有各向异性射流淬火参数的整体增强与增加磁场。此外，我还得出结论，对于这两个模型的横向动量展宽是在横向方向比在磁场的方向。由于这些结论被证明持有两个相当不同的全息设置在有限的温度和磁场，他们建议作为强耦合各向异性磁化等离子体的相当强大的功能。
