Local-photon model of the momentum of light

Gabriel Waite, Daniel Hodgson, Ben Lang, Varghese Alapatt, Almut Beige

AI总结:

本文基于局域光子方法将光的动量定义为空间平移生成元,分析光子波包进入致密介质时的动量动力学,为亚伯拉罕-闵可夫斯基之争提供新见解,并揭示与闵可夫斯基理论及量子电动力学正则动量定义的关键差异。

摘要:

最近我们引入了一种局域光子方法来模拟位置空间中的量子化电磁场。在本文中,我们利用这一方法,像量子力学中那样将光的动量定义为空间平移的生成元。随后,我们分析了从空气进入更致密介电介质的光子波包的动量动力学。我们的分析为亚伯拉罕-闵可夫斯基之争提供了新的视角,该争论凸显了表征电磁场动量所涉及的复杂性。尽管我们的结果与闵可夫斯基理论以及量子电动力学中光正则动量的定义一致,但也存在一些关键差异。

英文摘要:

Recently we introduced a local photon approach for modelling the quantised electromagnetic field in position space. Using this approach, we define the momentum of light in this paper as in quantum mechanics as the generator for spatial translation. Afterwards, we analyse the momentum dynamics of photonic wave packets which transition from air into a denser dielectric medium. Our analysis shines new light onto the Abraham-Minkowski controversy which highlights the intricacies involved in the characterisation of the momentum of the electromagnetic field. Although our results align with Minkowski's theory and with the definition of the canonical momentum of light in quantum electrodynamics, there are also some crucial differences.
