论文摘要
我们通过ADS/CFT对应关系探索磁场对QCD相变的影响。通过在爱因斯坦 - 马克斯韦 - 斯卡尔系统中引入各向异性磁场，通过潜在的重建方法获得了一个分析溶液家族，在黑色背景下磁场的贡献可以分析得出。通过要求$ j/ψ$介子的线性regge频谱施加动力学量表函数后，可以证明磁场相图的贡献。结果表明，随着磁场的增加，过渡温度将升高，这是所谓的磁催化效应。但是，如果系统处于足够强的磁性环境中，则过渡温度将冷却并显示反催化效果。
We explore the effect of the magnetic field on the QCD phase transition through AdS/CFT correspondence. By introducing an anisotropic magnetic field in the Einstein-Maxwell-Scalar system, a family of analytic solutions is obtained by the potential reconstruction method where the contribution of the magnetic field in the blackening background can be analytically derived. After imposing the kinetic gauge function by requesting the linear Regge spectrum of $J/ψ$ mesons, the contribution of the magnetic field phase diagram can be demonstrated. The results show that the transition temperature will be raising as the magnetic field increases, which is the so-call magnetic catalysis effect. However, if the system is in a strong enough magnetic environment, the transition temperature will be cool down and display the inverse catalysis effect.
