标题： The black hole interior and the type II Weyl fermions

摘要： 最近有提议认为，黑洞可能会经历一种转变，其中在视界内部形成费米面，这与最近发现的II型外尔半金属有相似之处。 在这种情况下，视界外部的低能有效理论是标准模型，它描述了假设的统一理论动量空间中某一点$P^{(0)}$附近的激发态。 在视界内部，低能物理是由动量空间中接近费米面的点处的激发态引起的。 我们认为这些点可能与$P^{(0)}$基本上相距很远，因此在黑洞内部，参与低能动力学的量子态无法由标准模型来描述。 我们分析了这一观察结果对黑洞物理的影响，并提出了一个基于与II型外尔半金属直接类比的模型，以说明这一模式。 显示英文摘要

摘要： It was proposed recently that the black hole may undergo a transition to the state, where inside the horizon the Fermi surface is formed that reveals an analogy with the recently discovered type II Weyl semimetals. In this scenario the low energy effective theory outside of the horizon is the Standard Model, which describes excitations that reside near a certain point $P^{(0)}$ in momentum space of the hypothetical unified theory. Inside the horizon the low energy physics is due to the excitations that reside at the points in momentum space close to the Fermi surface. We argue that those points may be essentially distant from $P^{(0)}$ and, therefore, inside the black hole the quantum states are involved in the low energy dynamics that are not described by the Standard Model. We analyse the consequences of this observation for the physics of the black holes and present the model based on the direct analogy with the type II Weyl semimetals, which illustrates this pattern.
