标题： Magnetic Monopoles and Duality Symmetry Breaking in Maxwell's Electrodynamics

摘要： 如何打破电荷和磁单极子之间具有对偶性的拉格朗日量的对称性，使得在低能情况下，电单极子相互作用仍然可以被观察到，但磁单极子相互作用变得非常高度抑制，以至于实际上消失。 源自由电磁动力学的“零电荷”问题通过要求在连续、局部的对偶变换下保持不变来解决，而局部对偶对称性与局部U(1)EM规范对称性的结合自然且意外地导致了SU(2)D对偶规范群。 显示英文摘要

摘要： It is shown how to break the symmetry of a Lagrangian with duality symmetry between electric and magnetic monopoles, so that at low energy, electric monopole interactions continue to be observed but magnetic monopole interactions become very highly suppressed to the point of effectively vanishing. The "zero-charge" problem of source-free electrodynamics is solved by requiring invariance under continuous, local, duality transformations, while local duality symmetry combined with local U(1)EM gauge symmetry leads naturally and surprisingly to an SU(2)D duality gauge group.
