猝灭的双味Einstein-Maxwell-Einstein规范引力模型
A quenched 2-flavour Einstein-Maxwell-dilaton gauge-gravity model
摘要：
我们通过引入具有两种夸克味的Einstein-Maxwell-Maxwell（EMD）作用来扩展早期的工作。在背景磁场存在的情况下，我们通过势重构方法在淬灭近似（探测夸克味）下求解相应的运动方程，寻找自洽的双磁AdS/QCD模型.作为一个应用程序，我们讨论的退禁闭转变温度确认逆磁催化，而对于中等值的磁场的熵密度也比较相对较好的过渡附近的相应的晶格数据。
英文摘要：
We extend earlier work by introducing an Einstein-Maxwell-dilaton (EMD) action with two quark flavours. We solve the corresponding equations of motion in the quenched approximation (probe quark flavours) via the potential reconstruction method in presence of a background magnetic field in search for a self-consistent dual magnetic AdS/QCD model. As an application we discuss the deconfinement transition temperature confirming inverse magnetic catalysis, whilst for moderate values of the magnetic field also the entropy density compares relatively well with corresponding lattice data in the vicinity of the transition.
