对于球对称蒸发黑洞背景下的有效场论，我们考虑了不可重整化的相互作用及其与物理效应的关系。背景几何是由半经典爱因斯坦方程确定的一个平静的视界，真空能量动量张量是自由落体的观察者很小。令人惊讶的是，霍金辐射出现后，从Unruh真空到某些多粒子态的跃迁振幅随时间指数增长的一类高阶导数算子后，塌缩物质进入近视界区域，尽管缺乏大曲率不变量。在混乱的时间内，平静的视界向防火墙过渡，最终有效场论崩溃。
For an effective field theory in the background of an evaporating black hole with spherical symmetry, we consider non-renormalizable interactions and their relevance to physical effects. The background geometry is determined by the semi-classical Einstein equation for an uneventful horizon where the vacuum energy-momentum tensor is small for freely falling observers. Surprisingly, after Hawking radiation appears, the transition amplitude from the Unruh vacuum to certain multi-particle states grows exponentially with time for a class of higher-derivative operators after the collapsing matter enters the near-horizon region, despite the absence of large curvature invariants. Within the scrambling time, the uneventful horizon transitions towards a firewall, and eventually the effective field theory breaks down.
