    Photon-photon scattering effects within the lab: When two green petawatt lasers’ beams collide at the focus of a third red beam to polarize the quantum vacuum, it enables a fourth blue laser beam to be generated—with a unique direction and color. Credit: Zixin “Lily” Zhang
    Simulations via advanced computational modeling recreate vacuum four-wave mixing—a quirky quantum phenomenon—and now this “solver” is poised to unleash new physics at extremely...
