摘要:

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。利用这些结果,在基于欧拉-海森堡-拉格朗日的有效场论的框架下,导出了三个初始波之间的预期耦合,并表明OAM为产生的光子增加了一个签名,从而大大提高了信噪比。这就为利用量子光学技术根据OAM状态过滤产生的光子的高功率激光实验奠定了基础

英文摘要:

In this letter, we investigate the effect of orbital angular momentum (OAM) on elastic photon-photon scattering in vacuum for the first time. We define exact solutions to the vacuum electro-magnetic wave equation which carry OAM. Using those, the expected coupling between three initialwaves is derived in the framework of an effective field theory based on the Euler-Heisenberg La-grangian and shows that OAM adds a signature to the generated photons thereby greatly improvingthe signal-to-noise ratio. This forms the basis for a proposed high-power laser experiment utilizingquantum optics techniques to filter the generated photons based on their OAM state
