Axion-电磁波
Axion-Electromagnetic Waves
摘要：
我们扩展的对偶对称性之间的电场和磁场的情况下，其中一个额外的类轴子项是本，我们推导出一套麦克斯韦方程组，保持这种对称性。这组新的方程允许一个规范对称性，扩展了经典电动力学中的普通对称性。我们获得明确的解决方案，在没有外部源的情况下，新的一组方程，我们讨论了一个新的内部对称性之间的轴子场和电磁规范位的影响。
英文摘要：
We extend the duality symmetry between the electric and the magnetic fields to the case in which an additional axion-like term is present, and we derive the set of Maxwell's equations that preserves this symmetry. This new set of equations allows for a gauge symmetry extending the ordinary symmetry in the classical electrodynamics. We obtain explicit solutions for the new set of equations in the absence of external sources, and we discuss the implications of a new internal symmetry between the axion field and the electromagnetic gauge potential.
