Can light interact with light?
- whatshisface 2y agoYes, the electron box Feynman diagram contributes a self-interaction term to Maxwell's equations scaled to the fine structure constant to the fourth power. You can find it in the introduction to Griffiths. I believe it has been experimentally detected.
