标题： Anomalous character of the axion-photon coupling in a magnetic field distorted by a pp-wave gravitational background

摘要： 我们研究了在引力辐射影响下的轴子-光子耦合问题。 我们专注于在pp波引力背景下的轴子电动力学方程的精确解，针对两种初始恒定磁场的模型。 第一个模型描述了在具有单位折射率的引力波真空中初始恒定磁场的响应；第二个模型的特点是由于普通物质和/或暗物质的存在而规定的非单位折射率。 我们表明，这两种模型在引力波背景中表现出由轴子-光子耦合产生的电磁场的异常行为。 讨论了轴子暗物质在形成这种电动力学系统异常响应中的作用。 显示英文摘要

摘要： We study the problem of axion-photon coupling in the magnetic field influenced by gravitational radiation. We focus on exact solutions to the equations for axion electrodynamics in the pp-wave gravitational background for two models with initially constant magnetic field. The first model describes the response of an initially constant magnetic field in a gravitational-wave vacuum with unit refraction index; the second model is characterized by a non-unit refraction index prescribed to the presence of ordinary and/or dark matter. We show that both models demonstrate anomalous behavior of the electromagnetic field generated by the axion-photon coupling in the presence of magnetic field, evolving in the gravitational wave background. The role of axionic dark matter in the formation of the anomalous response of this electrodynamic system is discussed.
