论文摘要
我们研究了两种相对加速的观察者在一个四维超级倾斜的schwarzschild黑洞的柔软地平线上，两种相对加速的观察者可以看出，两种自由骨气和费米原场模式之间的纠缠。首先，我们将冲击波与近地平线的几何形状相关联，通过在其度量标准之间以及波形形式与软发函数之间的关系之间明确构造。然后，我们将相互信息和纠缠负性计算为这两个观察者之间纠缠的量度，并表明它们的角度依赖性在毛发范围内。我们还表明，对于消失的软发功能，我们的结果等于普通的Schwarzschild黑洞壳的结果。
We study entanglement between two modes of a free bosonic and fermionic field as seen by two relatively accelerating observers at the soft-hair horizon of a four-dimensional supertranslated Schwarzschild black hole. First, we associate the shock wave to the near horizon geometry by explicit construction of map between their metric as well as relation between wave form factor and soft hair function. We then compute mutual information and entanglement negativity as a measure of entanglement between these two observers and show that their angular dependence at the soft-hair horizon. We also show that for vanishing soft hair function our results are equal to that of an ordinary Schwarzschild black hole case.
