Colliding light Illustration of photon–photon scattering. Two green petawatt lasers beams collide at the focus. A third red beam polarizes the quantum vacuum. This allows a fourth blue laser beam to be generated, with a unique direction and colour. (Courtesy: Zixin (Lily) Zhang)
A computational paradigm that can accurately simulate interactions between powerful laser beams and
