论文摘要
我们以霍金，佩里和斯特罗辛格的观察为基础，即全球黑洞时空支持了大量柔软的毛发自由度，以使Almheiri，Marolf，Polchinski和Sully的防火墙论证为防火墙论证提供新的启示。我们建议软发金矿模式是在连接渐近和近地平线区域的经典过渡函数中编码的。柔软的头发携带的熵是黑洞熵的一部分，并在外部几何形状中编码。我们认为，输入的观察者在到达地平线之前会自动测量软模式的经典值，并且该测量实现了代码子空间投影，该投影可以重建内部运算符。我们使用柔软的头发动力学引入了防火墙的观察者依赖性概念，并表明，对于一个内部的观察者，它向内退到了黑洞内部：观察者在达到奇异性之前从未遇到防火墙。我们的结果表明，HPS Black Hole软头发在溶解AMP的防火墙中起着至关重要的作用。
We build on the observation by Hawking, Perry and Strominger that a global black hole space-time supports a large number of soft hair degrees of freedom to shed new light on the firewall argument by Almheiri, Marolf, Polchinski, and Sully. We propose that the soft hair Goldstone mode is encoded in a classical transition function that connects the asymptotic and near horizon region. The entropy carried by the soft hair is part of the black hole entropy and encoded in the outside geometry. We argue that the infalling observer automatically measures the classical value of the soft mode before reaching the horizon and that this measurement implements a code subspace projection that enables the reconstruction of interior operators. We use the soft hair dynamics to introduce an observer dependent notion of the firewall and show that for an infalling observer it recedes inwards into the black hole interior: the observer never encounters a firewall before reaching the singularity. Our results indicate that the HPS black hole soft hair plays an essential role in dissolving the AMPS firewall.
