论文摘要
在该理论的哈密顿公式中仔细分析了经典轴轴 - 电子动力学的能量摩孔保存。确定了电磁和轴向扇区之间的能量转移的术语。作为一种特殊应用,在静态磁场的背景下进行了轴向到光的Primakoff过程,并在定量上对轴突振荡的辐射自动阻尼进行了特征。阻尼时间与首选轴质量范围内的宇宙年龄相媲美。
Energy-momentum conservation of classical axion-electrodynamics is carefully analyzed in the Hamiltonian formulation of the theory. The term responsible for the energy transfer between the electromagnetic and the axion sectors is identified. As a special application the axion-to-light Primakoff-process in the background of a static magnetic field is worked out and the radiative self-damping of the axion oscillations is characterized quantitatively. The damping time turns out comparable to the age of the Universe in the preferred axion mass range.
