电磁对偶的经典电动力学与电荷量子化

Classical electrodynamics and electric charge quantization in electromagnetic duality.

讨论了双四维矢势电磁对偶的麦克斯韦方程组 ,提出了一种电荷量子化方法 ;由鞍点近似下的经典作用量 ,导出了荷电粒子的运动方程 ,并计算了体系的总角动量 .

By introducing doublet four-dimensional vector potentials the duality symmetric Maxwell {equations} are discussed and a way of the electric charge quantization is yielded. Also, the equations of motion for charged particles by the classical action presenting for a saddle point are decived, the total angular momentum of the system is calculated.
