本文首次研究了轨道角动量对真空中光子-光子弹性散射的影响。我们定义了携带OAM的真空电磁波方程的精确解。使用这些，三个初始波之间的预期耦合导出的有效场理论的基础上的欧拉-海森堡拉格朗日的框架，并表明OAM添加签名所产生的光子，从而大大提高了信噪比。这形成了利用量子光学技术基于其OAM状态过滤所产生的光子的拟议高功率激光实验的基础。
In this Letter, we investigate the effect of orbital angular momentum (OAM) on elastic photon-photon scattering in a vacuum for the first time. We define exact solutions to the vacuum electromagnetic wave equation which carry OAM. Using those, the expected coupling between three initial waves is derived in the framework of an effective field theory based on the Euler-Heisenberg Lagrangian and shows that OAM adds a signature to the generated photons thereby greatly improving the signal-to-noise ratio. This forms the basis for a proposed high-power laser experiment utilizing quantum optics techniques to filter the generated photons based on their OAM state.
