摘要

在有效电磁动力学(EEMD)模型理论中研究了电磁场和轴子场之间的振荡和耗散能量交换，这意味着轴子与假设的磁荷共存。给出了电磁扇区和轴子扇区之间能量传递的精确公式。在第一个例子中，我们解析地计算了恒定静态磁场和周期性振荡轴子凝聚共同作用下产生的均匀振荡电场和磁场构型。在第二个例子中，在EEMD模型中计算了引力束缚轴子组态的电磁辐射能量损失。因此，在EEMD中也发现了一个渐近的[公式:见文本]簇大小随时间的增加。

Electromagnetic energy transfer processes in effective electro-magneto dynamics of axions

Oscillating and dissipative energy exchange between the electromagnetic and axion fields is investigated in an effective electro-magneto dynamical (EEMD) model theory, implying the coexistence of axions with hypothetic magnetic charges. An exact formula is presented for the energy transfer between the electromagnetic and axionic sectors. In a first example, we compute analytically the homogeneously oscillating electric and magnetic field configurations generated by the combined action of a constant static magnetic field and a periodically oscillating axion condensate. In the second example, the electromagnetic radiative energy loss of a gravitationally bound axion configuration is computed in the EEMD model. As a result, an asymptotic [Formula: see text] temporal increase of the clump size is found also in EEMD.
