具有极小初始自能的相干波分量可以显著改变收缩时空的首次响应。我们在具有两个对易类空Killing场的爱因斯坦-麦克斯韦-标量理论中展示了这一效应。沿着由标量化黑洞内部启发的临界族，估计的磁延迟为纵向传播重新分布入射场留出了时间。在固定初始电磁能量下增加低频分量，在一个背景上增强了标量响应，在另一个背景上则抑制了它。一种传播场及其动量、然后传播其二次标量和几何源的计算，在非线性演化之前预测了这一反转。在首次抑制比较时，相干轮廓误差为0.38%，而省略交叉项时为46.9%。选定的响应发展为一个具有电和标量交换的磁脉冲。因此，临界几何将入射相干性保留为信息，该信息预测了其首次偏离Kasner纪元的行为。
英文摘要
A coherent wave component with extremely small initial self-energy can substantially change the first response of a contracting spacetime. We demonstrate this effect in Einstein--Maxwell--scalar theory with two commuting spacelike Killing fields. Along a critical family motivated by scalarized black-hole interiors, the estimated magnetic delay leaves time for longitudinal propagation to redistribute the incident field. Increasing a low-frequency component at fixed initial electromagnetic energy enhances the scalar response on one background and suppresses it on another. A calculation that propagates the field and its momentum, then their quadratic scalar and geometric sources, predicts this reversal before nonlinear evolution. At the first suppression comparison, the coherent profile error is $0.38\%$, against $46.9\%$ when cross terms are omitted. The selected response develops into a magnetic pulse with electric and scalar exchange. The critical geometry thus preserves incident coherence as information that predicts its first departure from a Kasner epoch.
