没有防火墙的模型
A model with no firewall
摘要：
我们构建了一个模型，说明了模糊球互补猜想。在模糊球范式中，黑洞微观态没有内部，从它们的表面通过能量量子$E\sim T$幺正地辐射。但是带有$E\gg T$的量子撞击在模糊球上会产生模糊球表面的大的集体激发。这种激励的动力学必须作为超空间中的演化来研究，超空间是所有模糊球解$|F_i\rangle$的空间。在这个超空间中的状态被安排在一个“复杂性”的层次结构中。我们认为，进化向更高的复杂性地图，通过类似于AdS/CFT的二元性，落入传统的洞的视野内。我们解释了如何大退化的模糊球状态导致故障的等效原理在阈值的视界形成。我们记得，在考虑互补图像时，防火墙论证并没有援引$E\gg T$的极限;相反，它关注的是对霍金辐射有贡献的$E\sim T$模的动力学。这个漏洞允许模糊球互补中的对偶描述。
英文摘要：
We construct a model which illustrates the conjecture of fuzzball complementarity. In the fuzzball paradigm, the black hole microstates have no interior, and radiate unitarily from their surface through quanta of energy $E\sim T$. But quanta with $E\gg T$ impinging on the fuzzball create large collective excitations of the fuzzball surface. The dynamics of such excitations must be studied as an evolution in superspace, the space of all fuzzball solution $|F_i\rangle$. The states in this superspace are arranged in a hierarchy of `complexity'. We argue that evolution towards higher complexity maps, through a duality analogous to AdS/CFT, to infall inside the horizon of the traditional hole. We explain how the large degeneracy of fuzzball states leads to a breakdown of the principle of equivalence at the threshold of horizon formation. We recall that the firewall argument did not invoke the limit $E\gg T$ when considering a complementary picture; on the contrary it focused on the dynamics of the $E\sim T$ modes which contribute to Hawking radiation. This loophole allows the dual description conjectured in fuzzball complementarity.
