论文摘要
这项工作建立了弯曲空间中手性异常与重力场的辐射含量之间的关系。特别是，我们表明，圆形极化引力波的通量触发了从量子真空的净圆极化的光子的自发产生。使用波形目录，我们将进攻二进制黑洞识别为发射此类重力辐射的天体物理构型，然后以数值相对性求解完全非线性的爱因斯坦方程，以评估净效应。合并的量子幅度可与最终黑洞的鹰发射率相当，并且很小可直接观察到。但是，正如在对称的基础上所论证的那样，对二进制中子星的灵感的影响可能更为突出。
This work establishes a relation between chiral anomalies in curved spacetimes and the radiative content of the gravitational field. In particular, we show that a flux of circularly polarized gravitational waves triggers the spontaneous creation of photons with net circular polarization from the quantum vacuum. Using waveform catalogues we identify precessing binary black holes as astrophysical configurations that emit such gravitational radiation, and then solve the fully non-linear Einstein's equations with numerical relativity to evaluate the net effect. The quantum amplitude for a merger is comparable to the Hawking emission rate of the final black hole, and small to be directly observed. However, the implications for the inspiral of binary neutron stars could be more prominent, as argued on symmetry grounds.
