论文摘要
我们引入了一种新的探针，旨在跟踪霍金对的量子信息内容，这是距黑洞地平线距离的函数。我们通过半经典的复制方法计算此鹰对探针的熵含量，该方法依赖于自由田的灯芯收缩及其在黑洞地平线区域的领先顺序重力反应。我们发现，从黑洞状态到鹰对的信息传递是由几何过渡触发的，令人惊讶地发生在距地平线的宏观距离处。我们将计算与有关冯·诺伊曼代数在全息图中的作用的最新见解联系起来。
We introduce a new probe designed to keep track of the quantum information content of a Hawking pair as a function of the distance from the black hole horizon. We compute the entropy content of this Hawking pair probe via a semi-classical replica method that relies on free field Wick contractions and their leading order gravitational back reaction on the black hole horizon area. We find that the information transfer from the black hole state to the Hawking pair is triggered by a geometric transition that, somewhat surprisingly, takes place at a macroscopic distance from the horizon. We relate our computation to recent insights about the role of von Neumann algebras in holography.
