In this paper, gauge invariance of the electromagnetic field, gauge transformations of potential, the relation between degrees of freedom of gauge and physical degrees of freedom of the electromagnetic field are discussed. 本文讨论了电磁场的规范不变性、势的规范变换、规范自由度及其与物理自由度的关系等问题。
This paper proves that the derivative expansion method violates the gauge invariance at each expansive order, but the physical result we get by the sum of all of the expansive orders is gauge invariance. 本文证明,虽然导数展开法在逐级展开中破坏了规范不变性,但由各阶的和所得的物理结果是规范不变的。
A physical consequence of the gauge invariance in the process π~ 0 →γγ 规范不变性在π~0→γγ过程中的一个物理推论
In view of AB effect, the objective reality is not the gauge invariance in matter itself, but the invariance of the same logic implication in matter itself. 在量子力学中,由阿哈罗诺夫和玻姆提出的AB效应表明,物质的客观实在性并不一定体现在物质本身的变换不变性上,而是体现在物质本身的同一逻辑蕴涵效应具有不变性。
Although local gauge invariance leads to a non conservation Noether charge, the differential equation satisfied by the Noether current includes the charge conservation law of the charged field. 本文将论证如下结论:尽管定域U(1)规范不变性导致一个不守恒的Noether荷,但Noether流在形式上的守恒方程包含着带电场的电荷守恒定律。
