摘要：
我们利用全息方法证明，受磁场作用的强耦合等离子体所发射的光子，无论其四动量如何，均为线偏振，仅当光子沿磁场方向传播时例外。该引力对偶是通过10维IIB型超引力的5维截断构建的，除恒定磁场外还包含一个标量场。就我们所建模的碰撞实验几何而言，我们的结论是，该实验中产生的任何光子都必然处于唯一的、与反应平面平行的偏振态。
英文摘要：
We use holographic methods to show that photons emitted by a strongly coupled plasma subject to a magnetic field are linearly polarized regardless of their four-momentum, except when they propagate along the field direction. The gravitational dual is constructed using a 5D truncation of 10-dimensional type IIB supergravity, and includes a scalar field in addition to the constant magnetic one. In terms of the geometry of the collision experiment that we model, our statement is that any photon produced there has to be in its only polarization state parallel to the reaction plane.
