The anomalous nanoscale electromagnetic field arising from light–matter interactions in a nanometric space is called a dressed photon. While the generic technology realized by utilizing dressed photons has demolished the conventional wisdom of optics, for example, the unexpectedly high-power light emission from indirect-transition type semiconductors, dressed photons are still considered to be too elusive to justify because conventional optical theory has never explained the mechanism causing them. The situation seems to be quite similar to that of the dark energy/matter issue in cosmology. Regarding these riddles in different disciplines, we find a common important clue for their resolution in the form of the relevance of space-like momentum support, without which quantum fields cannot interact with each other according to a mathematical result of axiomatic quantum field theory. Here, we show that a dressed photon, as well as dark energy, can be explained in terms of newly identified space-like momenta of the electromagnetic field and dark matter can be explained as the off-shell energy of the Weyl tensor field.

壳外量子场将装扮的光子与宇宙学联系起来

纳米空间中光与物质相互作用产生的异常纳米级电磁场称为修整光子。虽然通过使用修饰光子实现的通用技术已经摧毁了光学的传统智慧，例如间接跃迁型半导体出人意料的高功率光发射，但修饰光子仍然被认为是难以证明的，因为传统的光学理论已经从未解释导致它们的机制。这种情况似乎与宇宙学中的暗能量/物质问题非常相似。对于这些不同学科的谜语，我们以类空间动量支持的相关性的形式找到了解决它们的共同重要线索，根据公理量子场论的数学结果，没有它，量子场就不能相互作用。在这里，我们展示了修饰的光子以及暗能量可以用新发现的电磁场类空间动量来解释，而暗物质可以用外尔张量场的壳外能量来解释。
