基于有效场论的模型描述了量子信息从黑洞内部到大气层的传输。这种描述说明，这种转移不需要对半经典几何或落入的观察者来说是暴力的，特别是可以避免产生单一的地平线或“防火墙”。人们可以具体量化信息传递的速率，并表明将黑洞蒸发单一化所需的速率会对地平线附近的应力张量产生相对温和的修正。在对转移的外部描述中，负责转移的新的相互作用被作用于黑洞大气中的场的“有效源”近似。如果必要的相互作用耦合到黑洞大气中的一般模式，人们还可以找到一种直接的机制，在开采黑洞时增加信息传输率，从而避免自相矛盾的行为。在这种新的相互作用存在的情况下，讨论了小黑洞和大黑洞的对应极限，后者的近视界描述近似于Rindler空间。
Transfer of quantum information from the interior of a black hole to its atmosphere is described, in models based on effective field theory. This description illustrates that such transfer need not be violent to the semiclassical geometry or to infalling observers, and in particular can avoid producing a singular horizon or "firewall." One can specifically quantify the rate of information transfer, and show that a rate necessary to unitarize black hole evaporation produces a relatively mild modification to the stress tensor near the horizon. In an exterior description of the transfer, the new interactions responsible for it are approximated by "effective sources" acting on fields in the black hole atmosphere. If the necessary interactions couple to general modes in the black hole atmosphere, one also finds a straightforward mechanism for information transfer rates to increase when a black hole is mined, avoiding paradoxical behavior. Correspondence limits are discussed, in the presence of such new interactions, for both small black holes and large ones; the near-horizon description of the latter is approximately that of Rindler space.
