论文摘要
加速电荷发出电磁辐射和重力辐射。从经典上讲，已经发现，单色平面波中电子辐射的电磁能谱与相应的引力范围成正比。从机械上讲，量子表明，重力生产和康普顿散射的幅度在树水平上相互成比例。在这里，通过结合强场QED和量子重力，我们证明了在任意平面波中非线性重力光生物生产的幅度与非线性康普顿散射的相应振幅成正比。同样，引入经典幅度我们证明，比例性依赖于平面波和能量摩托明保守法中电子运动的半经典性质，从而在经典和量子情况下导致相同的比例性常数。这些结果加深了重力和电磁学之间的交织在一起，既涉及非线性和量子水平。
Accelerated charges emit both electromagnetic and gravitational radiation. Classically, it was found that the electromagnetic energy spectrum radiated by an electron in a monochromatic plane wave is proportional to the corresponding gravitational one. Quantum mechanically, it was shown that the amplitudes of graviton photoproduction and Compton scattering are proportional to each other at tree level. Here, by combining strong-field QED and quantum gravity, we demonstrate that the amplitude of nonlinear graviton photoproduction in an arbitrary plane wave is proportional to the corresponding amplitude of nonlinear Compton scattering. Also, introducing classical amplitudes we prove that the proportionality relies on the semiclassical nature of the electron's motion in a plane wave and on energy-momentum conservation laws, leading to the same proportionality constant in the classical and quantum case. These results deepen the intertwine between gravity and electromagnetism into both a nonlinear and a quantum level.
