论文摘要
我们将标准的麦克斯韦在1+3维度中的理论考虑在及时边界的存在下。在这种情况下，我们表明（广义）Ampere-Maxwell的电荷似乎是与满足空间保护方程的Maxwell U（1）仪表对称性相关的NOETHE电荷。此外，我们还介绍了空间内存场的概念及其相应的内存效果。最后，通过Strominger的三角形建议的镜头类似，我们展示了空间记忆和保护是如何相关的。
We consider the standard Maxwell's theory in 1+3 dimensions in the presence of a timelike boundary. In this context, we show that (generalized) Ampere-Maxwell's charge appears as a Noether charge associated with the Maxwell U(1) gauge symmetry which satisfies a spatial conservation equation. Furthermore, we also introduce the notion of spatial memory field and its corresponding memory effect. Finally, similar to the temporal case through the lens of Strominger's triangle proposal, we show how spatial memory and conservation are related.
