论文摘要
我们使用有效的动作技术证明了电动力学和重力中量子头发的存在。在电动力学的情况下，我们使用Euler-Heisenberg的有效作用，而在量子重力的情况下，我们使用独特的有效作用。我们提供了这些效果的一般表述，这些效应适用于理论，并讨论它们之间的类比及其差异。此外，我们提出了一个对黑洞蒸发的QED类似物。电荷球外场的自发对产生类似于黑洞的鹰辐射。假设球形对称性，高斯定律会阻止外场取决于球的密度曲线。量子校正违反了这些期望，表明量子辐射可以经典地编码有关该来源的信息。
We demonstrate the existence of quantum hair in electrodynamics and gravity using effective action techniques. In the case of electrodynamics we use the Euler-Heisenberg effective action while in the case of quantum gravity we use the unique effective action. We give a general formulation of these effects which applies to both theories and discuss analogies and differences between them. Furthermore, we present a QED analog to black hole evaporation. Spontaneous pair production in the external field of a ball of charge is analogous to Hawking radiation from black holes. Assuming spherical symmetry, the Gauss law prevents the external field from depending on the density profile of the ball. Quantum corrections violate these expectations, showing that quantum radiation can encode classically forbidden information about the source.
