标题： Graviton-photon conversions in Euler-Heisenberg nonlinear electrodynamics

摘要： 我们研究在均匀且恒定的磁场环境中，考虑电动力学中的Euler-Köckel-Heisenberg型非线性修正下的引力子-光子转换。 我们为引力子采用横向无迹规范，并同时使用场势以及电和磁(EM)场来描述光子。 非线性修正导致宇称破坏(手征)的引力子传播方程，这些方程依赖于对光子的两种处理方式。 因此，介质对于引力波的两种极化表现出有效的双折射特性，类似于由非线性修正引起的光子双折射特性。 在存在引力的情况下，由于势与电磁场之间存在非平凡的关系，使用电磁场来呈现结果非常重要。 显示英文摘要

摘要： We study graviton-photon conversions in an environment of the uniform and constant magnetic field considering Euler-K\"ockel-Heisenberg-type nonlinear corrections in electrodynamics. We take the transverse-tracefree gauge for gravitons and employ both the field potential and the electric and magnetic (EM) fields for photons. The nonlinear correction causes parity violating (chiral) graviton propagation equations, which depend on the two treatments for photons. Thus, the medium becomes effectively birefringent for two polarizations of gravitational waves similar to the photon birefringence a characteristic of the nonlinear correction. In the presence of gravity, due to the nontrivial relation between the potential and EM fields, it is important to present the result using the EM fields.
